It could be, or it could be looking for something else that isn't a library 
and failing without giving a useful error message, or it could be a 
different problem entirely.

Think about how the web server is executing the program - there's no magic 
involved: it's setting some environment variables and executing it. You can 
replicate parts of this manually quite easily, which might get you useful 
information.

Suggested reading list: ldd(1), chroot(8), any logs produced by the 
programs involved (e.g. your CGI program and the web server).
