"man port" not working?

"We do not know how to turn this off."
I don't know if this may help, but in "man gcc", look at
GCC_EXEC_PREFIX
and look at
-B

In LIBRARY_PATH, it says, "(but directories specified with -L come first)"

Apparently -L is set with prefixes from -B.

"For each subprogram to be run, the compiler driver first tries the
           -B prefix, if any.  If that name is not found, or if -B was not
           specified, the driver tries two standard prefixes, which are
           /usr/lib/gcc/ and /usr/local/lib/gcc/."

"-B prefixes that effectively specify directory names also apply to
           libraries in the linker, because the compiler translates these
           options into -L options for the linker."
