You can use LIBsbcl_VERSION in the port Makefile. This can either
be passed to the build via a make variable (usually preferable)
or by patching (one option is to patch to ${LIBsbcl_VERSION},
SUBST_VARS+=LIBsbcl_VERSION, and use ${SUBST_CMD} to replace it, perhaps
in a pre-configure target).

Copy the clean original file to have the suffix .orig.port, edit,
then run "make update-patches" from the port dir. If you're using
SUBST_CMD then "update-patches" needs to be run at the right time.
