php-magickwand broken with ImageMagick 6.3.5.10

[Mike Bowie]

Good day all,

Per the subject, the build runs fine, but the magickwand extension no 
longer returns images and fails silently. <wink>

http://www.magickwand.org/ states:
** REQUIRED **  ImageMagick version :: 6.3.5-9
Last-known-good ImageMagick version :: 6.3.5-9

I upgraded ImageMagick due to the vulnerabilities listed in the 
portaudit database and after a handful of rebuilds, found that 
back-dating my ports tree to the previous version resolved the issue.

Perhaps someone could pop a version requirement / warning in the 
Makefile until such a time as support for 6.3.5.10 is included.

Much appreciated!

Cheers,

Mike.
