xgawk fails to build when expat is installed

[wnishida]

I encountered a build failure while installing xgawk @3.1.6a-20090408_2. Attached a log file. Thank you for your consideration.

We see these issues with libiconv all the time:

Whenever it's brought up 57821 and 43698 the issue always seems to be something not quite perfect with the way the port includes the headers and libraries.

It's certainly a PITA, though, as if you search for this error in MacPorts, you will find many many many examples of it.

Ryan and Josh seem to know the most about how to fix it.

Nothing too mysterious in this case, it's simply not linking with libiconv for some reason despite using its symbols.
