First time during a patching operation for me on OpenBSD.

I did

patch -p0 < 011_cvs3.patch

went through,

then

cd /usr/src/
cd gnu/usr.bin/cvs
make -f Makefile.bsd-wrapper obj
make -f Makefile.bsd-wrapper

This ends with:

In file included from /usr/src/gnu/usr.bin/cvs/src/client.c:81:
/usr/src/gnu/usr.bin/cvs/lib/xgssapi.h:20: gssapi.h: No such file or directory
*** Error code 1

*** Error code 1

Stop in /usr/src/gnu/usr.bin/cvs (line 24 of /usr/src/gnu/usr.bin/cvs/Makefile.bsd-wrapper).


Last time, for that earlier patch, it went through.

What am I doing wrong ?
