Going from MacPorts to Homebrew

Many blogs out there outline the process (1), (2), (3). Having upgraded to Ruby 1.9.3 and running into a segfault issue resolved by brew (https://github.com/capistrano/capistrano/issues/250) (http://bugs.ruby-lang.org/issues/5559), I thought it was time. So, I’m on the bandwagon.

First, following the official instructions, remove macports. Note: Macports installed mysql puts your db in /opt/local/var/db so back them up if you care. Also, check the official site for updates to these steps.

# Remove all installed ports
sudo port -fp uninstall installed

# cleanup remnants
sudo rm -rf \
/opt/local \
/Applications/DarwinPorts \
/Applications/MacPorts \
/Library/LaunchDaemons/org.macports.* \
/Library/Receipts/DarwinPorts*.pkg \
/Library/Receipts/MacPorts*.pkg \
/Library/StartupItems/DarwinPortsStartup \
/Library/Tcl/darwinports1.0 \
/Library/Tcl/macports1.0 \
~/.macports

Now install Homebrew as outlined on the official site. Note: Check the website before running this script as it may change.

<code id="selectable">ruby <(curl -fsSkL raw.github.com/mxcl/homebrew/go)</code>

Then follow the prompts.

Now, ready to install the rest of the stuff.

brew install imagemagick

I did opt to install mysql directly from oracle: http://www.mysql.com/downloads/mysql/ following (4).

In order to rebuild my rvm gemsets, I could have done it the ‘easy way’, but I preferred slash and burn:

# Completely remove RVM
rvm implode
# re-install rvm
bash < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer) 
# reinstall ruby
rvm install ruby1.9.2-p290

Here, rvm informed me that Ruby needs gcc to compile and xcode 4.4.1 doens’t come with it and to do the following in another terminal window:

brew update
brew tap homebrew/dupes
brew install autoconf automake apple-gcc42
rvm pkg install openssl

Now it is ready to continue to install ruby
