Hi,

In perl scripts (unix), one can do #!/usr/local/bin/perl BEGIN { $ENV{LD_LIBRARY_PATH} = ...; }
I've not tested this (what a great line to start a post...), but see if this works for you: #! /usr/bin/env LD_LIBRARY_PATH=/path/to/libs runhaskell which also has the (desirable? Hmm...) side effect of letting env figure out (using PATH) where to find runhaskell. This doesn't work for compiled binaries, sadly. Modifying LD_LIBRARY_PATH at runtime works for Perl because libraries are loaded at runtime, and the language allows you to sneak in some code before that happens. Even if Haskell had a System.Environment.withEnv (it already has a withArgs), it's probably too late to patch the environment -- you can't get in before the linker. (Unless you're using some sort of funky dynamic plugin thing.) Cheers, /Liyang
