Hello! Since a few years recent versions of bison (3.8.2), findutils (4.6.0, 4.7.0) and m4 (1.4.19) fail to build on my Apple PowerBook G4 with Tiger (Mac OS X 10.4.11) and/or Leopard (Mac OS X 10.5.8), and eleven years it failed for gzip (1.4) on someone other's Mac. The actual cause seems to be an ability of the MacPorts software (Tcl based) to remove the deep directory structure. From the shell or from inside GNU Emacs it works to overcome a "file name too long" error.
See these bug reports, particularly that for bison: https://trac.macports.org/ticket/63603 – bison 3.8.2 https://trac.macports.org/ticket/64373 and https://trac.macports.org/ticket/58927 – findutils 4.7.0 https://trac.macports.org/ticket/63059 and https://trac.macports.org/ticket/62994 – m4 1.4.19 https://trac.macports.org/ticket/50567 – findutils 4.6.0 https://trac.macports.org/ticket/28654 – actually gzip 1.4, eleven years ago -- Greetings Pete It isn't pollution that's harming the environment. It's the impurities in our air and water that are doing it.
