INSTRUCTIONS FOR GETTING MEMPROF WORKING ON SNOW LEOPARD

We'll compile and install a different version of ruby and ruby-gems alongside the default versions that ship with Snow Leopard.

Compile and install ruby

    Get ruby-1.8.7-p299.tar.gz (or the latest version) & untar it somewhere

    ./configure --prefix=/path/to/ruby/directory/you/want \
                --with-readline-dir=/opt/local \
                --with-iconv-dir=/opt/local \
                --enable-shared --enable-pthread \
                --disable-install-doc \
                optflags="-O0" \
                debugflags="-g3 -ggdb -ggdb3"

    I'm assuming you have readline and iconv packages installed to /opt/local (port install libiconv readline)

    make && make install

Compile and install ruby-gems

    Get ruby-gems-1.3.7.tgz (or the latest version) and untar.
    
    env GEM_HOME=/path/to/rubygems/directory/you/want ruby setup.rb -V

Edit your ~/.bashrc or ~/.bash_profile

    export PATH="/path/to/ruby/directory/bin:/path/to/rubygems/directory/bin:${PATH}"    # this is the install directory you picked above!
    export GEM_HOME="/path/to/rubygems/directory"                                        # this is the gems directory you picked above!

Install memprof gem

    gem install memprof --no-rdoc --no-ri

Done!
