Here's one I can successfully p/invoke:
otool -L /opt/local/lib/liballeg.dylib
/opt/local/lib/liballeg.dylib:

Here's the output from running my app with logging (good to know how to
do!):

I'm assuming wrong architecture means the library was built 64-bit but
should be 32. (or vice-versa?) I'm on snow leopard. This sounds more like a
build system issue than a p/invoke issue, so I'll pursue this with the
Allegro developers. Thanks for your help.
