Hi,

I did some Googling, but I didn’t see anything about this particular  
issue. It seems that IronRuby (the latest release from rubyforge)  
ignores the RUBYLIB environment variable, leaving $: set to the default.

The only way to add local paths seems to be to use the -I command line  
arguments. While this works, I’m surprised that RUBYLIB isn’t  
supported. I was pleasantly surprised when I installed JRuby and fired  
it up to test things and noticed that I didn’t have to do anything  
different than in MRE to have it find files.

I didn’t see any issues about this on CodePlex, but I wanted to check  
before I entered one.

Cheers,

IronRuby is not as mature as JRuby.

Yeah, I know… 🙂 Still, this is one of the main features that I use  
when doing local development so I don’t have to remember/retype long  
command lines when I’m experimenting or running commands.
