i had similar problem and it cause by Mono 1.9 installation issue (bug???).
libgdiplus itself installed perfectly OK, but there is no dll-mapping
defined in Mono.

there are few ways to fix it (assuming Mono 1.9 installed in /mono/1.9/):

1. quick and NOT recommended in production.
add
    export LD_LIBRARY_PATH=/momo/1.9/lib:$LD_LIBRARY_PATH
into /mono/bin/mod-mono-server script (or mod-mono-server2)
and restart mod-mono through http://localhost/mono (or restart Apache)

2. define gdiplus.dll mapping for System.Drawing.dll
create System.Drawing.dll.config file:
  <configuration>
    <dllmap dll="gdiplus.dll" target="/mono/1.9/lib/libgdiplus.so"/>
  </configuration>
and copy it into /mono/1.9/lib/mono/gac/System.Drawing/***all-sub-dirs-here***/

i would expect that from Mono build/installer (why it does not?)

3. same as above, but in a simple way (i am using it myself)
add following line
  <dllmap dll="gdiplus.dll" target="/mono/1.9/lib/libgdiplus.so"/>
into /mono/1.9/etc/mono/config

hope it helps

p.s.:
version of libgdiplus MUST be same as Mono version.
usually it is located in /your/mono/root/lib/
