cannot build current HEAD with MIT kerberos

[swen]

Since today a configuration of
./configure --with-system-mitkrb5 --without-ad-dc

is failing the succeeding make

[swen at linux SSS]$ make
WAF_MAKE=1 python ./buildtools/bin/waf build
Waf: Entering directory `/home/swen/SAMBA/SSS/bin/default'
	Selected embedded Heimdal build
ERROR: Target 'gssapi' in directory /home/swen/SAMBA/SSS/source4/heimdal_build re-defined as LIBRARY - was SYSLIB
make: *** [Makefile:8: all] Error 1

Did something change ?
Do I miss something obvious ?

Thanks for your support in advance.

Cheers Swen
