[las_users] MySQL/LAS 6.5.1.2/Mandriva 10.2 problem solved; now a perl path problem

[Hartmut Frenzel <frenzel@xxxxxxxxxxxxxxxxxxxxx>]

Hello,

first I'd like to thank Rob for solving my problem with MySQL - 
commenting out
#MYSQLD_OPTIONS="--skip-networking"
in
/etc/sysconfig/mysqld
did the trick. (This should probably be pointed out in the installation
documentation, as it will affect everyone with a recent version of MySQL.)

Now the LAS interface starts up as it should:

http://quercus.igpp.ucla.edu:8080/las/servlets/dataset

Select either dataset and any variable, and when it comes to actually 
drawing a plot, an error occurs:

Can't locate MD5.pm in @INC (@INC contains: ../xml/perl ../xml/perl/TMAP

Initially I had this problem with module PathConvert.pm. As it has been 
discussed before, i.e.
http://ferret.pmel.noaa.gov/Ferret/LAS/Mail_Archives/fu_2003/msg00033.html
this module is deprecated. I replaced all occurrences of 
File::PathConvert with File::Spec in these files:

xml/perl/LAS.pm
xml/perl/LASDB.pm
xml/perl/LASServlet.pm
xml/perl/LASUI.pm
xml/perl/LAS/Server.pm

For the release, this should be done in several *.pl and *.pl.in files 
in the bin subdirectory as well, and that should be all to replace the
PathConvert module.

Back to MD5: I have the file in (starting from the $LASDIR):
xml/perl/install/lib/perl5/site_perl/5.8.7/MD5.pm

which seems to be a directory that's listed in the @INC path above - if 
the starting point is one directory level below $LASDIR. If 
server/LASserver.pl is the main routine, this is the case, so I don't 
know why the module isn't found.

How can I fix this problem?

Thanks a lot!
