Compiling Ruby on Mac OS X Snow Leopard

Question

I am trying to follow this tutorial, on the subject of compiling ruby and rubygems on Snow Leopard:
http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard

I have added this to my ~/.profile:

export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH"

But if I write: echo $PATH I get:

/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/usr/X11/bin

But in tutorial it says:

You should see /usr/local/bin at the beginning of the line returned by the system.

I have installed macports sometime ago and plenty of other software, perhaps it has changed the path.

Anyway, I have tried to proceed with the installation, so I have built ruby, I did:

./configure --enable-shared --enable-pthread CFLAGS=-D_XOPEN_SOURCE=1
make
sudo make install
cd ..

But when I do which ruby I get:

/usr/bin/ruby

And according to the tutorial that's wrong. Also if I do ruby -v I get the older version of ruby that was preinstalled on Snow Leopard and not the one I've compiled.

Thanks.

UPD:

This is content of my ~/.profile:

export PYTHONPATH="/Users/m/djangocode:$PYTHONPATH"

alias hibernateon="sudo pmset -a hibernatemode 5"
alias hibernateoff="sudo pmset -a hibernatemode 3"

export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH"

I have deleted ~/.bash_profile, so it has no impact.

Here is the content of /etc/bashrc:

# System-wide .bashrc file for interactive bash(1) shells.
if [ -z "$PS1" ]; then
   return
fi

PS1='\h:\W \u\$ '
# Make bash check its window size after a process completes
shopt -s checkwinsize

and /etc/profile:

# System-wide .profile for sh(1)

if [ -x /usr/libexec/path_helper ]; then
    eval `/usr/libexec/path_helper -s`
fi

if [ "${BASH-no}" != "no" ]; then
    [ -r /etc/bashrc ] && . /etc/bashrc
fi

I think their contents are Mac OS X defaults. I never touched these.

If I open terminal up and type echo $PATH I still get:

/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/usr/X11/bin

But if I do: source ~/.profile then I get what I need:

misha-macbookpro:~ m$ . ~/.profile 
misha-macbookpro:~ m$ echo $PATH
/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/usr/X11/bin

And there is no ~/.bashrc file.

It seems that ~/.profile doesn't get "sourced" on terminal's start up. What can cause that?

Answer 1

set something like this in your ~/.bash_profile:

PATH=/usr/local/bin:/opt/local/bin:/opt/local/sbin:$PATH

MacPorts is already changing your $PATH in that file, so make your modifications there (MacPorts is the /opt/local tree)

Answer 2

You should seriously consider Homebrew

Answer 3

Apple's Terminal uses the ~/.bash_profile, not a .bashrc nor a .profile. Yes, its a bit annoying.
