Problems with bsd.port.mk

["Alex Kirk" <alex@schnarff.com>]

I just did a "cvs up -PAd ports" to make sure I had the latest patch to 
devel/jdk/1.2-blackdown. When I attempted to make the package, though, I got 
some odd errors: 

"/usr/ports/infrastructure/mk/bsd.port.mk", line 1413: missing `in' in for
cipher value in ${PROBLEMS}
"/usr/ports/infrastructure/mk/bsd.port.mk", line 1413: Missing dependency 
operator
"/usr/ports/infrastructure/mk/bsd.port.mk", line 1417: Need an operator
Fatal errors encountered -- cannot continue 

I tried some other ports (math/calc, misc/mshell) just to see if it was 
related to that particular port, and I got identical errors there. 

Could someone please tell me if this is a problem with my local system, or 
just a bug in bsd.port.mk? 

Thanks,
