first component is now a package name+version/pattern, no more
executable/patchname/whatnot.
While there, introduce BUILD_USES_MSGFMT as shorthand to pull in
devel/gettext unless /usr/bin/msgfmt exists (i.e. on post-1.5 -current).
Patch by Alistair Crooks <agc@netbsd.org>
ISO/Edinburgh-style Prolog compiler. Compliant with Part 1 of the ISO
standard for Prolog. Covers all traditional Edinburgh Prolog features
and shares many features with Quintus and SICStus Prolog, including a
compatible module system. Very fast compiler, garbage collection (also
on atoms), fast and powerful C/C++ interface, autoloading,
GNU-readline interface. SWI-Prolog supports architectures with 32-bit
or greater (64-bit) word-length. Packages for process management,
TCP/IP, XML/SGML, RDF, and the GUI toolkit XPCE, are also available.
