OK - this aligns with what I guessed from the error messages.

So the  DYLD_LIBRARY_PATH is only used during compilation - and not
during execution, even without "make install"?

OK - so in homebrew (I can't speak for Macports) the issue is at the
moment only the one you discuss below.

OK - so can you give me any suggestions how I can solve this to make
GRASS at least compile on homebrew?

Speaking generally - is this really the right approach to take, i.e. use
the generated binaries to generate the help files during installation?
Wouldn't it be much easier to do this during installation?

The paths are in the grass script file? Or in others as well? 

Wouldn't it make sense to

1) split the generation of the help files from the build step into a
separate make target
2) call the make target for help pages as a last step in the install
step?

This might make packaging more difficult, but wouldn't it make the whole
process clearer?

It worked with Yosemite without problems. So this only needs to be done,
because of the issues you describe above?

Thanks for these clarifications.

I would very much appreciate if we could see to get the compilation and
installation working using homebrew so that there is at least one way of
t=running GRASS on El Capitan without having to interfere with the
security settings.

Thanks,

Rainer
