Need help with weird builderror

[Hans de Goede <j w r degoede hhs nl>]

Hi All,

See: 
http://buildsys.fedoraproject.org/logs/fedora-development-extras/30683-dia-0.96-1.fc7/

This bombs with the following error:
checking for python module gtk... yes
checking for headers required to compile python extensions... found
checking for libpython2.5.a... not found
configure: error: could not find files required to build python plugin
error: Bad exit status from /var/tmp/rpm-tmp.45933 (%build)

The piece from the configure script giving this error is:
py_config_dir="$py_prefix/lib/python${PYTHON_VERSION}/config"

py_makefile="${py_config_dir}/Makefile"
if test -f "$py_makefile"; then
  py_localmodlibs=`sed -n -e 's/^LOCALMODLIBS=\(.*\)/\1/p' $py_makefile`
  py_basemodlibs=`sed -n -e 's/^BASEMODLIBS=\(.*\)/\1/p' $py_makefile`
  py_other_libs=`sed -n -e 's/^LIBS=\(.*\)/\1/p' $py_makefile`

  if test -e "${py_config_dir}/libpython${PYTHON_VERSION}.a"; then
    PYTHON_LIBS="-L${py_config_dir} -lpython${PYTHON_VERSION} $py_localmodlibs
    echo "$as_me:$LINENO: result: found" >&5
echo "${ECHO_T}found" >&6
  else
    echo "$as_me:$LINENO: result: not found" >&5
echo "${ECHO_T}not found" >&6
  fi
else
  echo "$as_me:$LINENO: result: not found" >&5
echo "${ECHO_T}not found" >&6
fi


The Makefile and libpython2.5.a files this piece of bash script looks for are 
both in python-devel (verified on my local machine), python-devel is in the 
BuildRequires and according to root.log does get installed. Also according to 
root.log the python package getting installed is the exact same version as on 
my devel machine, which does have this packages?

So what am I missing? HELP!

Regards,

Hans
