If you use the >=3D$version construct in a DEPENDS line, it forces the
ports system to check that a specific port is installed, as well as
ensuring that the version requirement is met.
Alternately, look at the databases/mytop port I maintain. There it uses
the standard form of dependency checking, like so:
RUN_DEPENDS=3D
${SITE_PERL}/${PERL_ARCH}/DBD/mysql.pm:${PORTSDIR}/databases/p5-DBD-mysql=
\
ie. it checks for the existence of a specific file. It doesn't matter
what port provides that file -- if any -- so long as the file exists,
the dependency is satisfied. Only if the file is missing will the port
install the suggested databases/p5-DBD-mysql to fulfil that dependency.
So you can install p5-DBD-mysql51 and mytop will happily co-exist if
installed after it.
Now, version 2.9003 of p5-DBD-mysql was current around April 2005 --
version 3.0000 came out on 30 June 2005. Is it still really necessary
to protect against installing software incompatible with that version?
Cheers,
Matthew
