I copied pg_sphere into the contrib directory in 8.1.0, which is where it was
built.  Last night, I executed a <make clean> from contrib/pg_sphere, re-built
<make> and re-installed.  I checked the pg_sphere Makefile, and it references
local, not absolute paths.

So, I'm as sure as I can be right now.  How can I check the .so files installed
by the build?  Do they reference an absolute path for their dependent .so files
(postgres), or will they use ld.so.conf, which might then explain the problem. 
My ld.so.conf still points to the 8.0.2 version, as I've not switched yet to
8.1.0.

In any case, why would the <make installcheck> work in the pg_sphere directory? 
That would have to use the installed libraries.  I don't have the sources with
me, but I'd think an index would of been created on a spoint column, but maybe
not?
