No, but I made an example for you, you can use this:
HAVE_TOR_DEVEL!= if ls /var/db/pkg | grep tor-devel-\* >/dev/null
2>&1 ; then echo YES; fi;
You should decide which one to use as a default. Let's say it is tor.
.if defined(HAVE_TOR_DEVEL)
RUN_DEPENDS+= ${LOCALBASE}/bin/tor:${PORTSDIR}/security/tor-devel
.else
RUN_DEPENDS+= ${LOCALBASE}/bin/tor:${PORTSDIR}/security/tor
.endif
Or if you want to make tor-devel the default one:
.if !defined(HAVE_TOR_DEVEL)
RUN_DEPENDS+= ${LOCALBASE}/bin/tor:${PORTSDIR}/security/tor
.else
RUN_DEPENDS+= ${LOCALBASE}/bin/tor:${PORTSDIR}/security/tor-devel
.endif
Or you can make it better by giving a knob for selecting the default.
The only problem is with my example, it does not respect PKG_DBDIR, but
I think it is better then just adding a pkg-message for the user to make
decision. I could not use ${PKG_DBDIR} in the evaluation somehow, it did
not work. This is not a big deal, though, people don't often override
that I think.
