lang/php53 and pbulk

[Manuel Bouyer <bouyer%antioche.eu.org@localhost>]

Hello,
since the last security pullup to 2013Q2, lang/php53 doesn't build any more
with pbulk (it seems to build fine in a manual build). The reason is that
at some point the php54 version is used instead of the php53 one,
as can be seen in 
http://nyftp.netbsd.org/pub/pkgsrc/packages/reports/2013Q2/NetBSD-5.1-x86_64/20130828.0632/php-5.3.27nb2/checksum.log

The attached patch fixes the issue. I guess it's needed because pbulk
iterates over allowed php versions.
Any idea if it's the right fix, or how to fix it properly ?
