In spite of its not being documented in bsd.port.mk (hello? portmgr?
anyone?) there is an alternate way to describe the dependency that would
fix this problem:

BUILD_DEPENDS=	lazarus-gtk2>=1.23:${PORTSDIR}/editors/lazarus-gtk2

That tells the dependency tracking to look for a specific installed port
with version >= 1.23, or else build/install it. This method should *not*
be used where it isn't really needed, but it's very useful when it is.
