FreeBSD 6.2 ImageMagic port fails test 1 of 700

Portupgrading my FreeBSD 6.2 machine and saw ImageMagic failed. Tried a
manual build to see what error codes I'd get and the end of the build looked
like this:

/usr/ports/graphics/ImageMagick/work/ImageMagick-6.4.7-5/tests/.libs/constit

Anyone know how I might fix this?
