This isn't picked up automatically. pkg.m4 is in /usr/share/aclocal/, and that 
seems to need some incantation of the aclocal command to work. I don't kow what 
that incantation is. Perhaps someone does, and can give me a hint.

Could you please try changing that AC_PATH_PROG (line 353 of configure.ac) to 
AC_PATH_TOOL (same syntax) as perhaps a simpler way of resolving the problem?
