I've installed RC5 in two places. In both, the installation worked at 
first. But after stopping tomcat, I had to add the jrrd directory 
explicitly to LD_LIBRARY_PATH before starting tomcat again.

I used
 ant tomcat-shutdown
and
 LD_LIBRARY_PATH=<blah>/perfsonar/contrib/rrdjtool/build ant \
   tomcat-start

Is this the right way?

And what is the right incantation to use after you've changed 
rrd-database_XXX.xml? Does it make a difference if the exist database is 
in use?
