Thanks Matthew, the following i did:

import common ;

COPY = [ common.copy-command ] ;

exe genversion : genversion.c : <define>VERSIONDIR=. ;

# at the moment the genversion tool is a bit restricted
# The version.def file must be in the same place as where genversion is
executed
# It generates a header file in ../include
actions make_version_c
{
        $(COPY) $(>[2]) $(BUILDPATH)/version.def
        cd $(BUILDPATH)
        $(>[1]:P)/genversion
}
make version.c : genversion version.$(CURBU).def : @make_version_c ;
