[rrd-developers] Re: calling rrd_create directly in librrd.so

Does this happen on the first rrd call or subsequent ones?  If it's 
subsquent you need to be resetting optind and opterr.  I've just been
through this loop.  The worrying thing is I've found it faster (10%)
to build a system call and run it than it was to link in the libraries.
