Build problems

[UweM]

Hello!

After a source update, the build process breaks.
Following steps:
1. cvsup /usr/share/examples/cvsup/DragonFly-supfile
2. cd /usr/src
3. cvs -d /home/dcvs update
4. cd /usr/dfports
5. cvs -d /home/dcvs update
6. cd /usr/src
7. make buildworld
Message:

cd /usr/src/gnu/usr.bin/cc34/cc_tools//../cc_prep; make depend
make: don't know how to make version.c. Stop
*** Error code 2
Any ideas? Thanks in advance.

Bye
Uwe
