(unknown charset) new make vs security/vpnc

Using recent head and the latest ports as of now.
$ cd /usr/ports/security/vpnc
$ make
===>  Building for vpnc-0.5.3_8
/usr/ports/security/vpnc/Makefile:37: *** missing separator.  Stop.
*** Error code 1

But fmake works just fine without any error.

In my ports tree Makefile:37 is:
.include <bsd.port.options.mk>

Please advise.
