mesa-libEGL-devel used to provide pkgconfig(egl), but it seems that disappeared in the latest build, breaking libepoxy and possibly others: Problem: package wxGTK3-devel-3.0.4-10.fc31.x86_64 requires gtk3-devel, but none of the providers can be installed - package gtk3-devel-3.24.10-2.fc31.x86_64 requires pkgconfig(epoxy) >= 1.4, but none of the providers can be installed - conflicting requests - nothing provides pkgconfig(egl) needed by libepoxy-devel-1.5.3-3.fc31.x86_64
rawhide (f32) *and* f31 are affected (koji builds currently fail in both).
Quick-n-dirty fix/workaround would be to drop from epoxy.pc Requires.private: gl egl and manually add Requires: libGL-devel libEGL-devel or Requires: mesa-libGL-devel mesa-libEGL-devel to libepoxy-devel
Will bodge up a build while upstream sorts their stuff out
