I'm going to take a stab in the dark here and suggest it's because you
have multiple (different) copies of iconv.dll on your PATH.

I get this on my current setup, where I've been messing around trying
to recompile lynx against iconv. I also get a popup saying "The
procedure entry point libiconv_set_relocation_prefix could not be
located in the dynamic link library iconv.dll."

Doing this worked for me:

C:\>set PATH=C:\Program Files\Common Files\GTK\2.0\bin
C:\>"C:\Python24\python.exe" -c "import ctypes; print
ctypes.CDLL('librsvg-2-2')"
<CDLL 'librsvg-2-2', handle 68e40000 at bd9b50>

Change the paths to your equivalents and try it, see if you have the
same or a similar dependency problem.
