Well, already had a working build, which reports though in the logfile somewhere:
```
-- The C compiler identification is GNU 4.4.5
-- The CXX compiler identification is GNU 4.4.5
-- Check for working C compiler: /usr/bin/gcc
-- Check for working C compiler: /usr/bin/gcc -- works
```
So, in effect it did pick the one supplied via OS, not the intended one.

* I have experimented a bit with preconfigopts/configopts but the desired behavior does not get delivered...
any ideas why? Can I assume that builddependencies sets up the PATH as it should?
