Ouch, we solved this one before and I'm trying to dredge it from
memory.  I *believe* the problem is that the PROJ_INFO was created
with an older version of GRASS than is needed by v.proj.  We have
been going in the other direction (SP to UTM) and we needed to 
create a brand new UTM location under GRASS4.1.  This made the
later version of the PROJ_INFO, which I then copied back over the
old one in our main location.  I think it is the "a" and "es" that
were missing.

Our current PROJ_INFO looks like:
	name: UTM
	proj: utm
	ellps: clark66
	a: 6378206.4000000004
	es: 0.0067686580
	zone: 10

and our State Plane (California) looks like:
	name: State Plane
	proj: lcc
	a: 0.63782064e+07
	es: 0.6768657997291094e-02
	x_0: 0.6096012192024384e+06
	y_0: 0
	lon_0: 122dw
	lat_0: 37d40'n
	lat_1: 39d50'n
	lat_2: 38d20'n

I believe that these work for us.
