Liams-MacBook-Pro:~ liam$ port -v installed readline
The following ports are currently installed:
  readline @6.1.000_1 (active) platform='darwin 10' archs='x86_64'

Liams-MacBook-Pro:~ liam$ lipo -info /opt/local/lib/libreadline.dylib
Non-fat file: /opt/local/lib/libreadline.dylib is architecture: x86_64

You have readline installed for x86_64, and are now trying to build it for i386, and the readline build is finding the old already-installed library of the wrong architecture instead of the new one it just built. To overcome this, you would deactivate the currently-installed readline (sudo port deactivate readline) before trying to build a new one.

However, why are you now trying to build for i386? Have you deliberately set build_arch to i386 in macports.conf? If so, then that's fine; if not, reconsider, because x86_64 is the usual architecture to use on Snow Leopard. If you are deliberately trying to build for i386 now, you'll have an easier time if you first uninstall all existing ports since they were built for x86_64.

Replying to ryandesign@…:

You have readline installed for x86_64, and are now trying to build it for i386, and the readline build is finding the old already-installed library of the wrong architecture instead of the new one it just built.

Sorry, I misread... you have readline installed for x86_64, and are now trying to build pcre for i386. It is peculiar that MacPorts did not attempt to rebuild readline for i386 on its own, since, as you showed above, it knows it's built for x86_64, and should know that it needs to rebuild it for i386. Still, my advice above holds: if you are deliberately switching build_arch, uninstall existing ports first.
