Add rubygems bin to PATH bug #145267

[Thufir]

This bug is quite annoying:


The rubygems package places the binaries for installed gems into /var/lib/
gems/1.8/bin, but this directory is not in the default PATH after the 
package is installed. It would be nice to add this when installing the 
package.

(I have to disagree a bit with the above description, in that the path to 
the gem should be the users directory.)

I suppose what's annoying, for me, is that it's not limited to this 
package, but more of a general problem, which solution is unclear to me.

Do you edit ~/.bashrc?  or, is it /etc/profile?  or, /etc/profile.d/
foo.sh, or ~/.config/autostart or ~/.kde/Autorun?  All have been 
suggested with varying rationales.

Sure, ok, "one true path" sounds like a great idea.  However, it seems 
pretty straightforward that *any* package should also set the path, 
should it not?

In this case, since gems are installed into the users folder, the path 
should be dependent upon the user.  In any event, is there at least a 
consensus on where to update the path?
