Hi, Some projects on Github provide handmade distribution tarball (let us call it H-tarball) for a release. The contents of this H-tarball could be essentially different from the check-out'ed source. The latter being identical to the autogenerated tarball (let us call it A-tarball), which we get with USE_GITHUB construct in the port's Makefile. H-tarball could contain files, which are missing from the A-tarball, such as: - configure script, - several Makefile's - documentation prebuilt from several formats In one example (which is expat, see below) - to build documentation (seems like) it requires this very expat to be installed in advance, thus bringing us to the cycle dependency. No wonder that the author of expat went into trouble and provided the H-tarball. Hence, building from A-tarball becomes a challenging task, which goes far beyond from saying "USES=autoreconf gmake" and "GNU_CONFIGURE=yes". Example for textproc/expat2 ver. 2.5.5: H-tarball: https://github.com/libexpat/libexpat/releases/download/R_2_2_5/expat-2.2.5.tar.bz2 source: https://github.com/libexpat/libexpat/tree/master/expat A-tarball: https://codeload.github.com/libexpat/libexpat/tar.gz/R_2_2_5?dummy=/R_2_2_5_GH0.tar.bz2 Playing with GH_* variables, I was able to fetch A-tarball within guidelines of bsd.sites.mk. But to fetch H-tarball, I could only invent the following: PORTNAME= expat PORTVERSION= 2.2.5 MASTER_SITES= https://github.com/libexpat/libexpat/releases/download/R_${PORTVERSION:S|.|_|g}/ Also, this project has declared that it moves from SF to GH. It still publishes H-tarballs on SF. But it seems that switching of the FreeBSD port to take distribution from GH is inevitable. Do you think that explicit MASTER_SITES instead of USE_GITHUB (thus using H-tarball) here contradicts to some rules of good stile? Do you think that fighting with A-tarball is always necessary? Regards, Sergei
