Need help with weird builderror

[Hans de Goede]

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
