https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D213636 --- Comment #10 from Kubilay Kocak <koobs@FreeBSD.org> --- (In reply to rsmith from comment #9) The word 'work' was specifically and intentionally not used, to focus just = on whether or not the USES=3Dpython:<version-spec> is incorrect as it relates = to what matplotlib is supposed to support (per upstream), not whether other factors (default options or other issues/bugs) prevent that from being true= at a certain point in time or in certain conditions (downstream). Keep in mind that USES=3Dpython:<version-spec> is a declarative specifier (= port supports this/these versions), not an imperative one (use this version) Looking back, ports r426883 (update to 1.5.3) states: - Additionally, 1.5.3 version doesn't build with python-3.X because 'import gtk' which the build tries fails in python3. Therefore, python:2. Based on this and on my reading of this issue (which may be incorrect or incomplete), this was and is an incorrect (at a minimum, imprecise) warrant and/or method for restricting builds to 2.7. 1) If the presence (or non-presence) or a build configuration (OPTION or OPTIONs in this case) prevents building with a particular version, then the restriction should be limited/scoped to that build option or build options,= not globally. 2) If a python package ('upstream python package' is meant here, not 'freeb= sd package') supports Python 2 and 3 builds, then the default configuration (r= ead: OPTIONS_DEFAULTS) of the port and it's dependencies should support building with 2/3 by default. Accordingly, and at a minimum: 1) USES=3Dpython:<version-spec> should be relaxed and be made to correctly reflect that matplotlib supports both Python 2 & 3.=20 2) The OPTIONS_DEFAULTS of this port should be modified to work with Python= 2 and 3 builds (if that is indeed possible). (1) and (2) alone are probably insufficient to ensure a good user experienc= e, if certain combinations of OPTIONS must be enabled/disabled to produce a va= lid Python 3 build environment, so: If certain options are mutually exclusive (in that some prevent Python 2 or= 3 builds), then OPTIONS_RADIO's or conditional blocks should be added that ch= eck for valid/invalid options combinations and inform the user with appropriate BROKEN/IGNORE/other methods when incompatible options/configurations are selected. --=20 You are receiving this mail because: You are on the CC list for the bug.=
