The code has a huge blob of hard-coded and heuristically determined configuration, and its too much of a mess for me to unpick in an arch-agnostic way, _AND_ there's no ENV directed mechanism to indicate when ExtUtils::F77's auto-magic is wrong. I've bodged around this in ExtUtils-F77's own test suite by constructing a "gfortran" inside the Tempdir and stuffing it in PATH, but that's only enough to demonstrate the code works, doesn't guard it against failing at the call points. This is subsequently not a "test failure", but a "real problem" that is exposed by a failing test, and dependent code will likely fail in the same way. ``` make -j3 --load-average=4 test TEST_VERBOSE=0 PERL_DL_NONLAZY=1 "/usr/bin/perl" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "undef *Test::Harness::Switches; test_harness(0, 'blib/lib', 'blib/arch')" t/*.t ExtUtils::F77: Using system=Linux compiler=GNU ExtUtils::F77: Unable to guess and/or validate system/compiler configuration ExtUtils::F77: Will try system=Generic Compiler=G77 ExtUtils::F77: Well that didn't appear to validate.

Let's see if this is better in 1.240.0 and later
Fixed in dev-perl/ExtUtils-F77-1.260.0
