As Richard says, we already have a couple packages that install into their own prefix.
E.g. lang/guile

The important lines are these:

GUILE_PREFIX=                   ${PREFIX}/guile/1.8
GNU_CONFIGURE_PREFIX=           ${GUILE_PREFIX}
BUILDLINK_PASSTHRU_DIRS+=       ${GUILE_PREFIX}
LDFLAGS+=                       ${COMPILER_RPATH_FLAG}${GUILE_PREFIX}/lib

and these in buildlink3.mk:

BUILDLINK_PASSTHRU_DIRS=                ${LOCALBASE}/guile/1.8
BUILDLINK_FILES.guile+=                 guile/1.8/bin/*
BUILDLINK_FNAME_TRANSFORM.guile+=       -e s,guile/1.8/bin,bin,
BUILDLINK_FNAME_TRANSFORM.guile+=       -e s,guile/1.8/lib/pkgconfig,lib/pkgconfig,
