Difficulty Installing on Fedora

[imorgans24582]

First issue, which is technically with libctl, but is solvable, is the version of guile installed with dnf installs as guile3.0, which autoconfig seemingly can't recognize except with export GUILE=/path/to/guile3.0, which in my case was export GUILE=/usr/bin/guile3.0.

The issue specific to MEEP is that it is seemingly impossible to get autoconfig to recognize libctl's location. To the degree I go the following build output:

checking how to activate readline in Guile... cannot
checking for libctl dir... /usr/local/share/libctl
checking for gen-ctl-io... gen-ctl-io
checking for ctl_get_vector3 in -lctl... no
configure: error: Couldn't find the required libctl library.

Any idea what is going on? Worth noting, on Fedora, the conda install seems to work, but I'd prefer to either build from source or install via pip rather than conda.

Look in the config.log file to see the error message when it tried to link -lctl.

Okay, it looks like a another guile issue, specifically from guile-ltdl. From the config.log:

guile-ltdl does not seem to be available in Fedora repos, or if it is, it is alias as something else that config can't find. For reference, on my system, if I type guil<tab>, this is what shows up:
guile1.8 guile1.8-config guile1.8-snarf guile1.8-tools guile3.0 guile-tools3.0

I have not aliased any of these; these are the default names they installed with. I have the same issue with MPB as well, and I can open a separately issue there if need be.
