build with clang fails for me

[Thomas Klausner <tk%giga.or.at@localhost>]

I've been building NetBSD with clang for some time now with:
build.sh -V DBG="-O2 -g" -V MKLLVM=yes -V HAVE_LLVM=yes -x -j 8 ...
but this stopped working a few weeks back.

Jan 16 worked, Feb 7 not. It still doesn't work with yesterday's clang update.

The failure is:

checking tool compatibility... ok
checking optional compiler flags... -Wno-variadic-macros 
-Wno-missing-field-initializers  -Wcovered-switch-default -Wno-uninitialized 
checking for python... result:: not found
no
checking for python >= 2.5... -c: not found
test: : bad number
not found
configure: error: found python  (); required >= 2.5
See `config.log' for more details.
*** [config/config.status] Error code 1
nbmake: stopped in /archive/cvs/src/tools/llvm
1 error

Does this work for anyone else? If yes, what does configure report at
this step?
