I am using MacOS Mojave version 10.14.16 and I am trying to install http://www.rpl2.net/index.php (a programming language using Reverse Polish Notation as found on some HP calculators like the 48GX), supposed to work on MacOSX (they say "MacOS X (Xcode 3.1.4 + gfortran 4.5)").
So I have downloaded the latest stable release, cd to the folder, and wanted to run
./configure
make
make install
But the ./configure is failing due to "configure: error: Can not find libgomp !". There is no libgomp package I can install with brew (I already installed gcc which comes with gfortran and thought it would provide libgomp but apparently not).
Could someone help a poor applied mathematician trying to install a software on its macbook?
Thanks
EDIT
in my config.log I have this, maybe it will help:

You don't say how you installed GCC. If you did it using homebrew, and
brew install gcc
you should be able to see:
/usr/local/Cellar/gcc/10.2.0/lib/gcc/10/libgomp.dylib
which would mean you need to compile with:
gcc ... -L /usr/local/Cellar/gcc/10.2.0/lib/gcc/10 -l gomp ...
Failing that, you can always search for libgomp with:
find /usr -name "lib*gomp*lib"
You can test which gcc you are using with:
type gcc
