In a nutshell, I compiled ruby-1.9.2 and installed it in my /home  
directory in order to isolate it from the rest of my system. Then, I  
aliased the ruby binary and scripts (~/ruby/bin) in my .bashrc to  
reflect the new installation (there is already a system-wide ruby-1.87  
installed). However, when I try to run gem or irb I receive the  
following gripe:

internal:lib/rubygems/custom\_require:29:in `require': no such file to load -- auto_gem (LoadError) from <internal:lib/rubygems/custom_require>:29:in`require’

I’m just not sure what it means. The ruby-1.92 interpreter runs fine, by  
the way.

The reason I’ve set things up the way I have is because Gentoo Linux  
does not play nice with ruby-1.9 yet. Any help is appreciated.

Naturally, after I sent out my SOS, the answer occurred to me. As it  
happens, Gentoo sets a system-wide environment variable, RUBYOPTS, that  
is not compatible or creates some sort of conflict. Sorry to  
inconvenience anyone.

Cheers!
