Comment:
Several things:

Just do `./autogen.sh` instead of what you currently have in pre_configure(). This fixes the error with missing `./configure`.

Also needs `pkg-config` in hostmakedepends to avoid missing macros in configure.ac.

Having pkg-config installed reveals the necessary makedepends `libXpm-devel`.
