I recently upgraded the OS on my Macbook Pro 13' to Mountain Lion (OS X 10.8). As a Ruby on Rails developer, supporting many environments is a must, and the biological and technological diversity of our clients require a plethora of tools to be installed and operational on my Macbook.
Anywho I found that this guide was helpful with the upgrade:

Thanks Prem and to all those who left a comment detailing their experiences on the subject. I too had my own bumps to iron out and have documented them here.
With Ruby: 1.9.3p-125 I ran:
gem install rails
This crashed when it was installing json-1.7.5 spitting out this message:
/usr/bin/gcc-4.2 not found
hmmm... since this was installed in the upgrade drill, i checked what was installed:
ls -ali /usr/local/bin/gc* 13662506 lrwxr-xr-x 1 themi staff 16 17 Sep 10:34 /usr/local/bin/gcc-4.2 -> ../Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2 13610191 lrwxr-xr-x 1 themi staff 47 16 Sep 15:16 /usr/local/bin/gcov-4.2 -> ../Cellar/apple-gcc42/4.2.1-5666.3/bin/gcov-4.2
ok great so...
sudo ln -s /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2 /usr/bin/gcc-4.2
(A similar fix is also mentioned in the remarks of the guide i followed)
BAM!! Back in business.
With Ruby: 1.8.7p-358 I ran
rake aborted! dlopen(/Users/themi/.rvm/gems/ruby-1.8.7-p358@core/gems/rmagick-2.10.0/lib/RMagick2.bundle, 9): Library not loaded: /usr/lib/libltdl.7.dylib Referenced from: /usr/local/lib/libMagickCore.5.dylib Reason: image not found - /Users/themi/.rvm/gems/ruby-1.8.7-p358@core/gems/rmagick-2.10.0/lib/RMagick2.bundle
Alright sounds like i need to upgrade something so...
brew update brew upgrade imagemagick bundle install
I found these solutions worked for others who had a similar issue:
gem pristine rmagick or brew remove imagemagick gem uninstall rmagick bundle install
RAILS_ENV=development lib/daemons/importerd_ctl.rb start
(This is a ruby file which spins up a daemon controller)
NOTE: I Typed:
then I got:
env: ruby\r: No such file or directory
Naturally it took me a while to realise what was up but I eventiualy got there...
rm -f ~/.bash_history
It turns out that the history file had escape codes in it that appear to be interpreted differently now.
So that was my experiences, I am very happy with Mountain Lion, sure there was no wow factor in the upgrade but its the small things that make up the total experience.
So I would like to close with my favourite quote:
"Man is the creator of change in this world. As such he should be above systems and structures, and not subordinate to them." - Steve Jobs
