[Mono-list] .so file not found in /usr/lib

[Daniel Hughes]

I have a library that I am trying to pinvoke to (libsword.so) that is
located in /usr/lib

This page:
http://www.mono-project.com/docs/advanced/pinvoke/
tells me that /usr/lib is on the search path.

However when I run my app I get a DllNotFoundException


If I run with: MONO_LOG_LEVEL=debug mono CSSword.Tests.exe

Then I get the following in the output:

Mono: DllImport attempting to load: 'libsword'.
Mono: DllImport error loading library
'/home/daniel/Work/sword/bindings/csharp/tests/bin/Debug/libsword':

Why is mono not finding the file in /usr/lib
