the 32 ports that still use it.  Bump PORTREVISION on their dependent
ports except the ones that depend on these:

audio/libogg
audio/libvorbis
devel/pcre
ftp/curl
graphics/jpeg
graphics/libart_lgpl
graphics/tiff
textproc/expat2
textproc/libxslt

In these cases the same trick as in the recent gettext update is used.
The ports install a symlink with the old library version.  When enough
of their dependent ports have had regular updates the remaining ones can
get a PORTREVISION bump and the links can be removed.

Also remove the devel/pcre dependency from USE_GNOME=glib20.  It causes
over 2200 packages to depend on devel/pcre while less than 200 actually
link with it.  The glib20 package still depends on devel/pcre so this
should not make a difference for ports with USE_GNOME=glib20.  Also,
libdata/pkgconfig/glib-2.0.pc lists pcre as a private library so
USE_GNOME=glib20 should not propagate it.
