 * I was just working on some tweaks to my SP port to ensure that it
 * compiles on old (2.1.x) systems as well as current.  One part of
 * the SP port for 2.2+ systems is a shared library, but on 2.1.x
 * systems, only the static library is built (linking against the
 * shared just produces core dumps).
 * 
 * My question is how to deal with a system version dependent PLIST. 
 * Ideas from more experienced porters? 

I just committed a change to bsd.port.mk to make things like this
easier to handle.

Basically, you use the variable ${PLIST} (defaults to
${PKGDIR}/PLIST).  So, you can prepare two complete PLISTs,

===
pkg/PLIST
pkg/PLIST-2.1
===

and do something like

===
version!=	uname -r | grep "2\\.1"
.if !empty(version)
PLIST=		${PKGDIR}/PLIST-2.1
.endif
===

Another way is to put the shared library stuff in a separate file, as
in

===
pkg/PLIST       (non-shlib stuff)
pkg/PLIST.shlib (shlib only)
===

and define

===
PLIST=	${PKGDIR}/PLIST.tmp
===

and then do a

===
version!=	uname -r | grep "2\\.1"
pre-install:
	${CP} ${PKGDIR}/PLIST ${PLIST}
.if empty(version)
	${CAT} ${PKGDIR}/PLIST.shlib >> ${PLIST}
.endif

pre-clean:
	${RM} ${PLIST}
===

The first one is obviouly easier for the Makefile, but you won't have
to update two PLISTs when you add one file.
