hi,

i’ve been including my libs using the RUBYLIB env variable, doing  
SET RUBYLIB=‘some path’

then running ir program.rb and it now has access to the files in ‘some  
path’

i also tried to do this dynamically in the ruby script using ‘system’.

i.e.

system ‘SET RUBYLIB=‘some path’’  
require ‘some.dll’ (where that file is in the path above’.

but it doesnt find the file. i assume ir is setting up the search paths  
when it starts up, is there anyway to achieve?

what i want is to be able to include a ruby file in my C# project, which  
can include all the dll’s in the projects bin easily. i guess i could  
just traverse the directory and do a require ‘file’ but the RUBYLIB path  
seems more flexible.

require ‘some.dll’
