[PLUG] Symlink syntax refresher

Found the problem building the grass source. It's look for libgeos-3.7.0.so
and my systems have libgeos-3.7.2 installed. On this system the libraries
are:

$ ll /usr/lib/libgeos*
-rwxr-xr-x 1 root root 1689316 May 20 08:55 /usr/lib/libgeos-3.7.2.so*
-rwxr-xr-x 1 root root     931 May 20 08:55 /usr/lib/libgeos.la*
lrwxrwxrwx 1 root root      16 May 20 08:56 /usr/lib/libgeos.so -> libgeos-3.7.2.so*

(it is /usr/lib64/ on those hosts).

I need to make a symbolic link so grass sees libgeos-3.7.0.so and it's been
a while since I've run 'ln -s ...'. The man page still doesn't clearly tell
me which is the target and which is the link name.

I _think_ what I need is libgeos-3.7.0.so -> libgeos-3.7.2.so and want to
confirm this before I make a mistake.

TIA,

Rich
