Drush install on RedHat 6 seems to do nothing I'm trying to get drush installed on a RHEL6 server. I've done the install via pear and also by unpacking the tar ball to /usr/local/share. Both methods result in the same result: typing "drush" from any location does nothing. To be more specific it hangs without any errors that I can see. 

It doesn't give any error about not finding it in the path, it just hangs.

I have had it working on other RHEL6 machines, but I haven't been able to pin down any differences between the installs to give me an idea what's wrong with this one.
Easiest way is to use the package manager:

yum -y install php-drush-drush


Alternatively, if it's installed in /usr/local/share then make a symbolic link:

sudo ln -s /usr/local/share/drush/drush /usr/local/bin/drush


Then, verify it works with:

which drush
