The solution how to run GTK Sharp MONO apps (compiled for example with Xamarin Studio) is to do following:

1. Compile your mono/gtk-sharp app as Release

2. Create shell script file (bash) like this (name it anyway you wish)

   [sharp]!/bin/sh
   
   export DYLD_FALLBACK_LIBRARY_PATH="/Library/Frameworks/Mono.framework/Versions/Current/lib:$DYLD_FALLBACK_LIBRARY_PATH:/usr/lib"    
   exec /Library/Frameworks/Mono.framework/Versions/Current/bin/mono ./AsketicExcel.exe
   

_3. Then you could run this form Terminal or you can use this packager tool http://sveinbjorn.org/platypus and create normal OSX App :) (include in the package all your files in Release dir)

Then in order to run this app on other mac you will need to install GTK# & Mono runtime http://www.go-mono.com/mono-downloads/download.html

In the end it would look like:

I have found the issue, my dllmap was incomplete.

I added the following lines to /Library/Frameworks/Mono.framework/Versions/2.10.9/etc/mono/config:

<dllmap os="osx" dll="libgtk-win32-2.0-0.dll" target="/Library/Frameworks/Mono.framework/Versions/2.10.9/lib/libgtk-quartz-2.0.0.dylib" />
<dllmap os="osx" dll="glibsharpglue-2" target="/Library/Frameworks/Mono.framework/Versions/2.10.9/lib/libglibsharpglue-2.so" />
<dllmap os="osx" dll="libgthread-2.0-0" target="/Library/Frameworks/Mono.framework/Versions/2.10.9/lib/libgthread-2.0.0.dylib" />
<dllmap os="osx" dll="libgthread-2.0-0.dll" target="/Library/Frameworks/Mono.framework/Versions/2.10.9/lib/libgthread-2.0.0.dylib" />
<dllmap os="osx" dll="libglib-2.0-0.dll" target="/Library/Frameworks/Mono.framework/Versions/2.10.9/lib/libglib-2.0.0.dylib" />
<dllmap os="osx" dll="libgobject-2.0-0.dll" target="/Library/Frameworks/Mono.framework/Versions/2.10.9/lib/libgobject-2.0.0.dylib" />

Ran into this issue aswell and although Fabian's answer was on the right track, it wasn't the solution for me. As per this bug filed with Xamarin, the following entries to the dllmap were required to be added to /Library/Frameworks/Mono.framework/Versions/Current/etc/mono/config (with a couple of duplicates removed).

<dllmap os="osx" dll="glibsharpglue-2" target="/Library/Frameworks/Mono.framework/Versions/Current/lib/libglibsharpglue-2.so" />
<dllmap os="osx" dll="gthread-2.0.0" target="/Library/Frameworks/Mono.framework/Versions/Current/lib/libgthread-2.0.0.dylib" />
<dllmap os="osx" dll="gthread-2.0" target="/Library/Frameworks/Mono.framework/Versions/Current/lib/libgthread-2.0.dylib" />
<dllmap os="osx" dll="glib-2.0.0" target="/Library/Frameworks/Mono.framework/Versions/Current/lib/libglib-2.0.0.dylib" />
<dllmap os="osx" dll="glib-2.0" target="/Library/Frameworks/Mono.framework/Versions/Current/lib/libglib-2.0.dylib" />
<dllmap os="osx" dll="glibsharpglue-2" target="/Library/Frameworks/Mono.framework/Versions/Current/lib/libglibsharpglue-2.so" />
<dllmap os="osx" dll="gtksharpglue-2" target="/Library/Frameworks/Mono.framework/Versions/Current/lib/libgtksharpglue-2.so" />
<dllmap os="osx" dll="gobject-2.0.0" target="/Library/Frameworks/Mono.framework/Versions/Current/lib/libgobject-2.0.0.dylib" />
<dllmap os="osx" dll="gobject-2.0" target="/Library/Frameworks/Mono.framework/Versions/Current/lib/libgobject-2.0.dylib" />
<dllmap os="osx" dll="gtk-quartz-2.0.0" target="/Library/Frameworks/Mono.framework/Versions/Current/lib/libgtk-quartz-2.0.0.dylib" />
