Really? Isn't enough to depend on the package name instead of a file?

No. The dependency installs files that are not otherwise installed, so the pkg-plist has to reflect that. Here's how I did it in the port I just created a slave for.

Created this section in the main port's Makefile:
.if defined(SLAVE)
OPTIONS_DEFINE+=        BROCCOLI
OPTIONS_DEFAULT+=       BROCCOLI
BROCCOLI_DESC=  Build support for libbroccoli communications
.endif

This adds the option and enforces it being selected if you install the slave port.

Then created this section in the main port's Makefile:
.if ${PORT_OPTIONS:MBROCCOLI}
PLIST_SUB+=     BROCCOLI=""
pre-configure:
       (cd ${WRKSRC}/aux/broccoli && ./configure)
pre-build:
       (cd ${WRKSRC}/aux/broccoli && ${MAKE})
post-build:
       patch ${BUILD_WRKSRC}/cmake_install.cmake ${FILESDIR}/broccoli.patch
.else
PLIST_SUB+=     BROCCOLI="@comment "
.endif

The PLIST_SUB section allows you to add files to the pkg-plist that are provisional, based on the install of the slave port.

Then the pkg_plist sub has the files included with the macro:
%%BROCCOLI%%include/broccoli.h
%%BROCCOLI%%lib/libbinpac.a
%%BROCCOLI%%lib/libbroccoli.a
%%BROCCOLI%%lib/libbroccoli.so
%%BROCCOLI%%lib/libbroccoli.so.5
%%BROCCOLI%%lib/libbroccoli.so.5.1.0

Those only get removed if the option was selected, so deinstall won't throw errors if you install the main port without that option.
