libkipi build fails from kde4 trunk

[Jasper Mackenzie-2]

Good day,
  I am not posting this as a bug yet as I am sure this is a local issue,
libkdcraw fails to build, with the following error:

which suggests problems with math.h

libc6-dev is version 2.7-10

any help would be appreciated.

cheers.

not math.h, because it's linking (not compilation).

i suspect than -lm is missing in linking gcc command line.
