[Grml] add-on to my last post - Error : C preprocessor "lib/cpp" fails sanity check when compiling Bacula 2.2.8 on grml 1.1 rc

[Peter]

Sorry, I forgot to add, that the bacula package I am talking about is 
the direct download from bacula.org  (current release 2.2.8)

Hi
Does anybody knows what that means ?
I made sure that I have build-essentials, linux-headers , gcc-4.2 , but
all this has already been on the dist.

I found many, many posts concerning this error on Google, but I just can
not figure out what it means in my context

Thanks for your help
Peter
