In directory usw-pr-cvs1:/tmp/cvs-serv8840/src

Modified Files:
	plcore.c 
Log Message:
Work a bit on the dynamic dirver location code for the post-install
context.  Currently we are storing the drivers and the database that
describes them, under $prefix/lib/drivers/*.  But plLibOpen doesn't
look there, as it uses DATA_DIR instead, which is
$prefix/lib/$plver/data.  So if our first attempt to load the drivers
database fails, try again with ../../ prepended, to bump up from
DATA_DIR to LIB_DIR.  

Similarly, when loading the actual driver, if the first load attempt
fails, resynthsize a full path (absolute, composed from LIB_DIR) and
try again. 

With these mods, I am able to use dynamic drivers inside the Java
binding, for clients using LD_LIBRARY_PATH = $plplot_prefix/lib.
