It turns out that my system installation of Automake is 1.9, but /usr/share/aclocal/upc.m4 did not exist. I've got 'upc.m4' in place now so it seems to make it pass 'aclocal' and 'automake' now. I've got another somewhat related issue, and that is: how can I conditionally use the macro AM_PROG_UPC? Most users won't have UPC in their path so I'd like to only check for UPC if the user configures explicitly with UPC. If I wrap the macro call like so: if test "xwith_upc" = "xyes" ; then AM_PROG_UPC fi I get "configure: error: conditional "am__fastdepUPC" was never defined. Usually this means the macro was only invoked conditionally.". In the configure script, it looks like UPC-related code is generated outside of my if..fi block in addition to inside of the block.
