It compiles OK with: sudo port install exim configure.compiler=llvm-gcc-4.2

Sorry, I forgot to put exim in the ports field.

This is actually #37834; you have an existing /tmp/buildconfig that is getting in the way.

Replying to jmr@…:

This is actually #37834; you have an existing /tmp/buildconfig that is getting in the way.

My port infrastructure is well past r103518 #37834 but I am still getting this bug. I have rebuilt the port infrastructure and installed it.

[jmroot (Joshua Root)]

It is the same issue as discussed in #37834, but caused in this case by exim's build system explicitly setting TMPDIR="/tmp".
