Hello Dr. Haas,

Many thanks for your reply.  I sincerely appreciate your time. 

The file is there:

$ ls /opt/local/include/gsl/gsl_sf_ellint.h

/opt/local/include/gsl/gsl_sf_ellint.h

Per your advice, I added:

 - "/opt/local/include/" to CPPPATH

 - "/opt/local/lib/" to LIBPATH

Now I get:

$ scons

scons: *** No SConstruct file found.

File "/opt/anaconda3/lib/python3.8/site-packages/SCons/Script/Main.py", line 944, in _main

Hello Krishiv,

you need to check that the include file is present eg for macports this
would be (something like):

/opt/local/include/gsl/gsl_sf_ellint.h

If that is not found the you will have to edit the SConstruct file you
are using to have the path "/opt/local/include/" in CPPPATH.

You then likely have to add "/opt/local/lib/" to LIBPATH.

Maybe someone on this list has a macOS+macports SConstruct file for
SelfForce1D that you could use.

Yours,
Roland
