Hi,

Welcome to the list!  Are you using the optionlist for fedora from simfactory?

	simfactory/mdb/optionlists/fedora.cfg

First, let's just check that the GSL package is still installed:

	dnf list installed gsl

If it is true that it worked a few weeks ago, and you haven't changed anything in the ET build, then it's possible that an update of Fedora has upgraded the GSL version, and the version which the ET links to is no longer available.  If so, then you might be able to fix the problem by wiping your ET configuration,

cd Cactus
rm -rf configs/sim

(or whatever configuration name you may have used instead of "sim"), and rebuilding as you did before.  The configuration stage will find the available GSL, and hopefully you won't get this error.
