Linux: Fedora: libVisionProxy.so requires libtiff.so.4 --- workaround

[Martin Thomas]

*** workaround
- needed *.so see comment #1

Making a symlink for libtiff.so.4 that points to the original libtiff.so.3 seems to work well.

---------------------------------------------------------

Requirements for the Linux version say:
"Make sure you have Java Runtime Environment (JRE) 6+, wmctrl, and OpenCV 2.1 (libcv2.1, libcvaux2.1, libhighgui2.1) installed. "

However, trying to run a script results in error message:
java.lang.UnsatisfiedLinkError: java.lang.UnsatisfiedLinkError: /home/martin/Downloads/Sikuli-X-1.0rc2-linux/Sikuli-IDE/libs/libVisionProxy.so: libtiff.so.4: cannot open shared object file: No such file or directory

Fedora 14, x64

Further, this library is directly required by libVisionProxy:
 readelf -d /home/martin/Downloads/Sikuli-X-1.0rc2-linux/Sikuli-IDE/libs/libVisionProxy.so

I think, the docs need a Linux section, that documents, how the dynamic libraries are linked and what they expect where to find.
