I've made buildroot overrides of openspecfun available.  But my scratch build https://koji.fedoraproject.org/koji/taskinfo?taskID=136362412 fails in %install with:

I don't understand why it's trying to re-configure during the install.  Maybe the doc build is messing with some timestamps?  Not sure why this is showing up in EL10.

This PR is ready to go - https://src.fedoraproject.org/rpms/gnuplot/pull-request/21  Comments would be welcome, otherwise I'll probably merge and build myself if I don't get any response.

Please branch and build gnuplot in epel10/10.1/10.0.

If you do not wish to maintain gnuplot in epel10,
or do not think you will be able to do this in a timely manner,
I would be happy to be a co-maintainer of the package (FAS orion);
please add me through https://src.fedoraproject.org/rpms/gnuplot/adduser

Will you be able to branch and build gnuplot in epel10?
I would be happy to be a co-maintainer if you do not wish
to build it on epel10 (FAS: orion).
