You'll need something like this:
---
.include <bsd.port.pre.mk>
.if exists(${LOCALBASE}/bin/wget) && !exists(${LOCALBASE}/bin/curl)
RUN_DEPENDS+= wget:${PORTSDIR}/ftp/wget
.else
RUN_DEPENDS+= curl:${PORTSDIR}/ftp/curl
.endif
---
You should be careful though to match this with your program's logic.
I.e. `what does it do if both wget and curl are installed?' The above
case is for `it uses curl then' answer.

No, you don't. clamav and clamav-devel are conflicting ports that
install the same files, so should you depend on clamav as
RUN_DEPENDS= clamscan:${PORTSDIR}/security/clamav
or
LIB_DEPENDS= clamav:${PORTSDIR}/security/clamav
if clamav-devel is installed instead, dependency will still match it and
it'll be used. Note `clamav', not `clamav.5' in LIB_DEPENDS.

is too slow, so it's better to create an index like that:
find -L /usr/ports -name Makefile -maxdepth 3 -mindepth 3 -exec grep -H '' {} \; > MAKEFILES.INDEX
