=46rom =E2=80=9C/usr/ports/Mk/Uses/python.mk=E2=80=9D:
concurrent - Indicates that the port can be installed for
different python versions at the same time. The port
is supposed to use a unique prefix for certain
directories using USES=3Duniquefiles:dirs (see the
uniquefiles.mk Uses for details about the
directories), if set to yes. Binaries receive an
additional suffix, based on ${PYTHON_VER}.
The values for the uniquefiles USES are set as
follows:
UNIQUE_PREFIX=3D ${PYTHON_PKGNAMEPREFIX}
UNIQUE_SUFFIX=3D -${PYTHON_VER}
If the port is installed for the current default
python version, scripts and binaries in
${PREFIX}/bin
${PREFIX}/sbin
${PREFIX}/libexec
are linked from the prefixed version to the
prefix-less original name, e.g.
bin/foo-2.7 --> bin/foo.
So it seems that any port that only installs modules in
=E2=80=9C/usr/local/lib/pythonX.Y/site-packages/=E2=80=9D could be labeled =
as concurrent as-is.
If your port wants to put things in DOCSDIR, EXAMPLESDIR, DATADIR, WWWDIR or
ETCDIR, you should add =E2=80=9CUSES=3Duniquefiles:dirs=E2=80=9D to your po=
rt's Makefile.
Also read =E2=80=9C/usr/ports/Mk/Uses/uniquefiles.mk=E2=80=9D.
