I've tried several different permutations of symlinks and none of them 
seem to fix it.

Slackware 10.0

Done.  Pasting previous conversation below.

There should be a mapping between libgdiplus.dll into libgdiplus.so.
It's strange that Mono is not able to find the right library. Are you
sure your mono is in the same prefix as libgdiplus's prefix? Also, it
might be that you need to add some more dirs to $LD_LIBRARY_PATH.


--------------CUT--------------


I just tried:
ln -s /usr/lib/libgdiplus.so [wwwroot]/bin/gdiplus.dll

Which produced the following stack trace when I try to load the same 
test page from before:

Is this at all helpful, or is this expected behavior for what I tried? 
1.1.4 is being released as the new latest stable version, you say? Well, 
as soon as the Mono website reflects that, I'll download and install. 
Hopefully that will fix this for me (and hopefully I won't break my 
existing functionality in the process).
