问题
I have been trying to install the TinyTDS gem on a Macbook with OSX 10.6. I was successful in installing Free TDS -- confirmed that it works via:
tsql -H SERVER -p 1433 -U username.
The error I'm getting from gem install tiny_tds is:
Building native extensions. This could take a while...
ERROR: Error installing tiny_tds:
ERROR: Failed to build gem native extension.

freetds is missing.

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
I've tried specifying the TDS lib and include dirs (/usr/local/lib and /usr/local/include) without luck. I've tried reinstalling FreeTDS from source manually as well as via homebrew, but that made no difference.
I've seen a few similar issues posted, but they seem to reference an issue with locating iconv libraries which I appear to be moving beyond.
Any suggestions or references I may have overlooked? Thanks in advance.

Same problem on Ubuntu 14.04 resolved with:
sudo apt-get install freetds-dev
gem install tiny_tds

You need to install freetds with homebrew
brew update # always a good idea to update homebrew before installing anything!
brew install freetds

In my case, it seems the symlinks were not configured correctly, and using "brew link freetds" threw errors which required opening up some permissions. I tried just about everything else, and this is finally what worked:
devMac:0.95.18 Me$ sudo chown -R $USER /usr/local/share/doc/freetds/images
devMac:0.95.18 Me$ sudo chown -R $USER /usr/local/share/doc/freetds/reference

devMac:0.95.18 Me$ brew link --overwrite freetds

Disclaimer: I am in the early stages of learning this framework and do not have an understanding of the repercussions of using overwrite or changing these permissions.

In my case, installing Ruby 2.3.0 using brew install ruby worked. I got the idea from this question Cannot install tiny_tds on os.x 10.9.4.
