Carol,
Changing the group membership of the LDM user shouldn't affect the installation
or running of the LDM because -- as the owner of the files -- the LDM user has
all the permission it needs.
The output of the configure-script contained this:
checking for libxml/parser.h... no
configure: error: Header-file not found
The libxml2 development package must be installed in order to build the LDM.
The prerequisites are listed at
<http://www.unidata.ucar.edu/software/ldm/ldm-current/basics/platform.html>.
When you've installed the prerequisite packages, then re-execute the
configure-script.
> I did removed the --enable-logging to the ./configure command, but it
