Let's start with the simple answer:

Can't locate auto/RRDs/latest.al in @INC at ./show-rrd-problem.pl line 41

Assuming you meant RRDs::last(), because it returns an irrelevant number.  Try it.  You'll find yourself missing every other few updates because ::last() returns the last update time of the file, and not the last timestamp value stored in the file.
