Thanks.
Maybe an even better solution would be to let the user specify the 
python binary and query the correct values from this binary:

e.g.:

PYTHON='python2.4'

PYTHON_INCDIR=`$PYTHON -c "import sys; \
   print sys.prefix + '/include/python' + sys.version[:3]"`

PYTHON_LIBS=`$PYTHON -c "import sys; \
   print sys.prefix + '/lib/python' + sys.version[:3]"`

Using this mechanism, the configure process will always find the correct 
executable/library/header combination.

I believe the user should be able to specify the _base_ directory for 
the man-page. But bacula.8.gz should always go to the man8 subdirectory 
of that base-dir. Suppose the package contains other man-pages that 
should go to other categories (e.g. for the config-files that should go 
to section 5). The user should supply the base-path and the man-pages 
should automatically be installed in the appropriate sections.

Look at the RPM-macro _mandir for example:
$ rpm -E '%_mandir'
/usr/share/man
