Hi,

I installed macruby 0.6 through rvm, but irb gave the following error  
message:  
$ irb  
No such file or directory - open() failed (Errno::ENOENT)

In fact, this irb program is a bash script, which exec macirb in the  
end:  
$ cat irb  
#!/usr/bin/env bash

export GEM\_HOME="/Users/liruohao/.rvm/gems/macruby-0.6"  
export  
GEM\_PATH="/Users/liruohao/.rvm/gems/macruby-0.6:/Users/liruohao/.rvm/gems/macruby-0.6@global  
"  
export MY\_RUBY\_HOME="/Users/liruohao/.rvm/rubies/macruby-0.6"  
export  
PATH="/Users/liruohao/.rvm/gems/macruby-0.6/bin:/Users/liruohao/.rvm/gems/macruby-0.6@global  
/bin:/Users/liruohao/.rvm/rubies/macruby-0.6/bin:$PATH"

exec “/Library/Frameworks/MacRuby.framework/Versions/0.6/usr/bin/macirb”  
“”  
“$@”

And if I remove the second string (which is empty) from the exec  
arguments,  
irb seems go quite well. Is this a bug or something (I’m not a bash guy,  
and  
don’t understand the exec statement with that empty string in the  
middle)?  
Thanks.
