Hello Timothy,

note: Please always c.c. the mailing-list as this could be useful to
other parties (now or in the future).

I'm really not a mod_mono expert - but someone else probably knows the
answer.

Yes, it means that your libgdiplus is there and doing it's job (i.e.
it's not a bug but a configuration issue).

My guess is that your mod_mono instance must be running under another
user account where the libgdiplus, or something it depends on, cannot be
found (since it's an unmanaged library the GAC or MONO_PATH are not
enough).
