Sorry, no seegar.  The order is:

		/lib
		/usr/lib
		/usr/local/lib

The above comment about stopping when a given library is found is quite true.
Has anyone thought about how to set up system programs arbitrary local
directories can be included in the search path?  There was a start at that
with /usr/include/local/uparm.h in 4.1BSD but very few programs use it.
Life is indeed difficult if you want to use /local/... instead of
/usr/local/...

For those of you with source take a look at ld.c sometime to see how the
directories are set up to be searched, truly a hack.  Reminds me of
v6...Ahhh the good ole days(I'm glad they're gone).  Troff does the same
stuff too.  For those that care this is for 4.?BSD.
