Comment (by i0ntempest):

 Figured it out: {{{${worksrcpath}libraries/terminfo/configure}}} was
 executed using an incompatible shell, due to a symlink that I created on
 my system. The script immediately exited with an unexpected operator error
 but the build process did not catch it and just continued on.

 We probably should find a way to force this script to be executed using
 {{{/bin/sh}}}. It's not respecting its shebang line.
