This was a very poor choice, we shouldn't have bumped the version. When
there is a bump between two minor releases (8.31 -> 8.32) a red led
should blink in port maintainer. The port should have defined:

USE_AUTOTOOLS=  libtool
USE_GNOME=      ltverhack

to avoid bumbing the version. In fact this is the diff in configure.ac:

-m4_define(libpcre_version, [1:1:0])
-m4_define(libpcre16_version, [0:1:0])
+m4_define(libpcre_version, [3:0:2])
+m4_define(libpcre16_version, [2:0:2])

It says that the new shared lib is compatible with the old lib (only new
interfaces were added), since:

1 - 0 = 3 - 2 = 1
1 - 0 = 2 - 2 = 0

(from the [current:revision:age] version = current - age rule)
