sci install error on linux: cannot find libgfortran.so.3; unusable after install

[maueroats]

Using Racket 8.10 on a "Ubuntu 22.04.3 LTS" linux system with both libgfortran5 and libgfortran-11-dev installed.

It looks like processing manual-flomat.scrbl immediately preceeds the build error.

Attempting to require flomat demonstrates the problem is real:

Source of problem is: custom built kernel does not pass the "ubuntu" test.

[maueroats]

See PR #17 There is no need to condition the version numbers of libgfortran on the linux distribution.

Closing. Thanks for PR #17
