Comment (by kprussing):

 Digging around a bit more, I found out that exec
 [https://comp.lang.tcl.narkive.com/V3aTqdvS/exec-problem#post3 creates a
 temporary file for standard error]. That led me to edit the pkg-config.tcl
 to redirect the standard error to prevent trying to create a file (below).
 I was able to edit the Portfile before running `port config neomutt -doc`
 and it configured. I was then able to build, destroot, and install. But
 I'm not sure this is the right solution. Running the resultant executable
 fails with a segfault.
