Odd.  Your perl(1) was built using gcc(1) and the netCDF and netCDF
packages appear to have been built using /usr/bin/cc, which should be
the same compiler on a Linux system.  Therefore, there should not have
been an undefined symbol.

The "make" output for the NetCDF-Perl package didn't contain any
compilation lines, so this needs to be checked.  Would you please

    1.  Go into the top-level source-directory.

    2.  Execute the command "make clean".

    3.  Execute the command "make".  Redirect both the standard output 
        and standard error streams to the file "make.log".

    4.  Send me the file "make.log".

Another thing that needs to be investigated is the location of the
symbol "__mth_i_kcmp".  Would you please try to locate it by executing
commands like

    nm -g /usr/lib/lib* | grep __mth_i_kcmp

Use the nm(1) option that prefixes every output line with the name of
the library.
