[hobbit] Moving RRDs from one version of rrdtool to another

[Charles Jones]

Indeed...it should be simple, but of course I'm having some unknown 
problem :)
# /usr/local/rrdtool-1.0.49/bin/rrdtool xport la.rrd
ERROR: can't parse 'la.rrd'
# ls -l la.rrd
-rw-r--r--    1 hobbit   other       19572 May 29 09:02 la.rrd

I truss'd the command and don't see any reason for it to fail. the last 
thing that happens before the failure is checking my timezone:
18476:  open("/usr/share/lib/zoneinfo/US/Arizona", O_RDONLY) = 3
18476:  fstat64(3, 0xFFBE68F0)                          = 0
18476:  read(3, " T Z i f\0\0\0\0\0\0\0\0".., 130)      = 130
18476:  close(3)                                        = 0
18476:  time()                                          = 1180454799
18476:  fstat64(2, 0xFFBE6548)                          = 0
ERROR: 18476:   write(2, " E R R O R :  ", 7)                   = 7
can't parse 'la.rrd'18476:      write(2, " c a n ' t   p a r s e  ".., 
20)      = 20

Meh.
