This is caused by a change to various ctype functions to do with
improved UTF8 support recently, which inadvertently broke ABI
compatability on RELENG_6.  The change has since been reverted, but
it seems that you were unlucky enough to install or upgrade some
software during the month or so that it was in place, so that it
is referring to symbols that do not exist in libc.so.

Perl is just one of the places where __sbmaskrune can show up.
There's been quite a lot of discussion of it on various lists
recently:

http://www.google.co.uk/search?hl=en&q=site%3Alists.freebsd.org+__sbmaskrune&btnG=Google+Search&meta=

This, precisely, is the commit message where the ABI breakage you've
seen was created:

http://lists.freebsd.org/pipermail/cvs-src/2007-October/082836.html

and here is where it was fixed:

http://lists.freebsd.org/pipermail/cvs-src/2007-November/084046.html

To sort out your system, basically make sure you're running a RELENG_6
version from after the fix was committed, and then I'm afraid you've
just got to reinstall any software that shows the symptoms.   Anything
installed before the original commit that broke things will be fine --
it's just software that was recompiled using a RELENG_6 system from
between 24 October and 20 November.

It's only RELENG_6 that was affected -- the change went into
RELENG_7 (and HEAD) where ABI changes are permitted with the new major
version number, but RELENG_6_2, RELENG_6_3 and other release branches
never had this patch applied.

	Cheers,
