Eh, I've seen this troublesome behaviour with x11-links too. What I do is
`cd' into the `x11-links' pkgsrc dir., run a `make distclean', then come back
to whatever I was trying to build.

The pkgsrc people might have a better solution.

I don't think the VAX has NAN (nor even IEEE-754 floating point capability).
Try either
 	#define NAN nan("")		// #include <math.h> needed
or
 	#define NAN (0.0f / 0.0f)

Also ask on port-vax@ to see how they handle the lack of IEEE floats.
