 This usually means /opt/local/lib/libexpat.1.dylib and
 /opt/local/lib/libfontconfig.1.dylib are not built for the same
 architecture, and therefore the loader tries to use
 /usr/lib/libexpat.1.dylib in place of /opt/local/lib/libexpat.1.dylib, but
 /usr/lib/libexpat.1.dylib is library version 7 and
 /opt/local/lib/libexpat.1.dylib is library version 8. It is the same
 problem as described in ProblemHotlist#libiconv-version for a different
 library.

 The solution is to build everything for the same architecture. MacPorts
 should do this automatically so something must have gone wrong on your
 system.

 Did you migrate from a previous OS version? If so, you must follow the
 wiki:Migration instructions.

 Please show us what architectures fontconfig and expat are actually
 installed for, and what architectures MacPorts thinks they're installed
 for, by running these commands:

 {{{
 lipo -info /opt/local/lib/libfontconfig.1.dylib
 /opt/local/lib/libexpat.1.dylib
 port -v installed fontconfig expat
 }}}
