I have done

port clean netpbm

I have tried

port install netpbm build.jobs=1

because of something i read about parallel builds not working

[blb@…]

Does the file /opt/local/lib/libnetpbm.dylib already exist? The message

ld: warning: in /opt/local/lib/libnetpbm.dylib, file is not of required architecture

suggests it does and is from a pre-10.6 install, in which case you need to first read the Migration page on upgrading.

Also, FYI, it builds fine here on 10.6.1, Xcode 3.2.
