Error installing Gimp-Gap

[Francis Ovenden]

I have been trying to install Gimp-gap on an iMac (2GHz Intel Core 2 
Duo, 1GB RAM) fairly unsuccessfully! I originally installed Xcode tools 
from the OS X 10.4 CD but went back and downloaded v2.5 from Apple, 
removed Macports and re-installed 1.52 including selfupdate. I was able 
to install and run Gimp 2.4 but Gimp-gap has consistently failed 
compiling msmpeg4. Anyone else come across this or know what is wrong?

Here's the listing with the error.
