Using RVM, I tried to install ree-1.8.7-2011.03 after installing Fedora 15 and I get the following error. Using rvm install ree-1.8.7-2011.03 on Ubuntu 11.04 wo
rvm install ree-1.8.7-2011.03
This also happens when installing ruby-1.8.7 with rvm in Fedora 15.
Reinier Balt's answer also works, in my case I had to install system wide ruby using yum.
Here's what I did:
cd ~/.rvm/src/ruby-1.8.7-p334/ext/dl ruby mkcallback.rb > callback.func ruby mkcbtable.rb > cbtable.func
