[Paraview] Permissions issue with ParaView-4.4.0-Qt4-Linux-64bit.tar.gz

[Eric Nodwell]

After unpacking ParaView-4.4.0-Qt4-Linux-64bit.tar.gz I was unable to
launch it. Attempting to launch it from the command line resulted in:

$ /opt/ParaView-4.4.0-Qt4-Linux-64bit/lib/paraview-4.4/paraview
/opt/ParaView-4.4.0-Qt4-Linux-64bit/lib/paraview-4.4/paraview: error
while loading shared libraries: libGenericIO.so: cannot open shared
object file: No such file or directory

Turns out that ParaView-4.4.0-Qt4-Linux-64bit/lib/paraview-4.4/libGenericIO.so
had the following permissions:

-rwx------. 1 1001 1001   378310 Sep 14 15:36 libGenericIO.so

So the fix is simple:

chmod a+r ~/shared/ParaView-4.4.0-Qt4-Linux-64bit.tar.gz

To be clear, I had installed it as,

sudo tar xvzf ~/Downloads/ParaView-4.4.0-Qt4-Linux-64bit.tar.gz -C /opt

Had I unpacked it without sudo, it would have run fine, although just
for me, not for other users.

Hope this is useful to others who might run into this minor issue.
