I found an answer to my problem regarding the use of mysql_read_default_file and my perl script crashing. According to:
http://www.rosat.mpe-garching.mpg.de/mailing-lists/dbi/2002-06/msg00159.html and a page referenced therein, MySQL v3.23.49 contains the problem and v3.23.50 fixed it. Damn, why doesn't Debian (woody distribution) include the .50 release yet. Hopefully my 8-9 hours spent seeking this answer will help someone else. -- Greg Thompson NCAR/RAP
