gimp2 on leopard

[Arden]

I have just started to use Macports on Leopard 10.5.4 (Intel),  
downloaded and installed the latest stable version, my aim is to use  
the GREYCstoration plugin for Gimp2. So lots of dependencies starting  
from scratch. Here is the error I get while it is building glib2:

ld: in /usr/local/lib/libJPEG.dylib, file is not of required  
architecture
collect2: ld returned 1 exit status
make[2]: *** [libglib-2.0.la] Error 1
make[1]: *** [all-recursive] Error 1

Macports installs the GREYCstoration plugin on Tiger (PPC) fine  
without error but on my MacBook it seems to have a lot more  
difficulty. Is this common for Leopard? how do I fix?
thanks, Arden
