serf1 fails to build for apr symbols

[rmottola (Riccardo)]

On 10.5 64bit I get this failure:

ld: warning: ignoring file /opt/local/lib/libaprutil-1.dylib, file was built for unsupported file format which is not the architecture being linked (x86_64)

I have no updates for apr, so I suppose it is current I am on 64bit so it is correct and the warning is confusing.

Actually... maybe the issue is apr.

$ file /opt/local/lib/libaprutil-1.dylib
/opt/local/lib/libaprutil-1.dylib: Mach-O dynamically linked shared library i386

so I have apr built for the wrong architecture, I have already seen something similar
