: It is doesn't cover those cases not using libtool and not using
: pkg-config either. Otherwise I have no major objection.

  I do: It adds hidden dependencies on expat, iconv, et al.  If
fontconfig were later updated to a newer version that doesn't use one
of these libraries (yet is ABI compatible), a binary package of
ghostscript would be broken.  While there may be no way around that on
IRIX (and AIX), it is not necessary on more capable platforms.


  So I think the best approach would be to use the buildlink3
framework to add the -l flags and dependencies on platforms that need
this.
