Conflict with libiconv version between /usr/lib and /opt/local/lib

[john_brownie@…]

Trying to get Bibledit to work on the Mac, I've worked through the list of required installs, and it now launches but crashes with a problem with libiconv versions:

Dyld Error Message:
  Library not loaded: /opt/local/lib/libiconv.2.dylib
  Referenced from: /opt/local/lib/libXft.2.dylib
  Reason: Incompatible library version: libXft.2.dylib requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0

To me it says that I'm getting the /usr/lib version of libiconv rather than the version in /opt/local/lib.

Part of getting to this point was to remove the definition of DYLD_LIBRARY_PATH from my .profile, which was apparently inserted when installing MacPorts.

I'm very much of a newbie when it comes to this part of development, so I'm looking for some guidance, but haven't been able to find anything that helps so far.

DYLD_LIBRARY_PATH was not inserted by MacPorts, but having it set will cause problems, so yes, please unset it.

The error "Incompatible library version: XXX requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0" usually means that the architecture of the two libraries does not match. What are their architectures? What architectures are you wanting to use? Is this an old MacPorts install from an old OS X version? If so, did you follow the Migration instructions?

OK, I had not realised that I had installed MacPorts in April 2010 and installing it now brought me the problems. Following the migration instructions fixed this particular issue. I now have a different one, but one that is hopefully easier for me to work on. Thanks!
