Okay, I stuided this a little after getting some zzz's, and its not
what I thought.

I got thorugh this by setting LD_LIBRARY_PATH so that it would find
the prefix area that I'm building against.  My memory is foggy, did we
ordinarily have to do this before?  Intuitively, I would expect the
software to build without LD_LIBRARY_PATH set, but probably not run
without it set (for prefixen not listed in ld.so.conf).  But usually I
have my LD_L_P set to the prefix in my .cshrc, but this came up this
time because I'm setting up a new prefix area.
