[gradsusr] about GrADS-2.2.0

Here is a tarball with my builds of the supplibs for CentOS7:
     ftp://cola.gmu.edu/grads/Supplibs/2.2/builds/supplibs-centos7.3-x86_64.tar.gz
In there you will find  .supplibs/bin and ./supplibs/lib and ./supplibs/include subdirectories. The libcairo.so and libgd.so files (and all the other libraries linked with GrADS) are in the ‘lib’ subdirectory. You can put these files anywhere, under your $HOME directory or in /usr/local/bin and /usr/local/include/ and /usr/local/lib if you prefer. If you put them under your $HOME directory, then you need to update the LD_LIBRARY_PATH environment variable to include $HOME/supplibs/lib.

> This line is an error message from the dlopen library. It looks like the field where the full path to libgxpCairo.so should be is empty — the file GrADS is looking for should be preceding that “:” at the beginning of your error message. Here is what I get when I put a bad filename deliberately (“foo”):

I use GAUDPT to point to my own personal plug-in functions and developer version of the graphics plug-ins, and $GADDIR/udpt to point to the official versions of the graphics plug-ins for every user on the server. The names in the $GAUDPT file override the names in the $GADDIR/udpt file. If there are errors in $GAUDPT GrADS will always use those first and then give up and quit before trying any other options.
