[ncl-install] NCAR Graphics on an IBM Sandybridge cluster

[George Vandenberghe]

I don't have root on this cluster. There is some resistance to 
installing additional packages because of the (small) decrement they 
make on available memory when a part of system directories so I often do 
nonstandard nonroot installations on the parallel filesystem instead.   
I had to install pixman-1 (trivial) cairo(hard), expat (trivial),  and 
bz2 (trivial).   Once I did this though, the gks library failed to 
compile properly because it needed freetype includes whose location has 
moved to a subdirectory of /usr/include/freetype2. I put these
into the (also changed) X search path and got everything except idt to 
compile and function properly. Locally built  idt isn't going to work 
until and unless I get a libXaw.a from our admins.
There is something very similar with a different name out there but I'm 
outside the NCEP secure environment and can't see it.. will check 
tomorrow.  Meanwhile the prebuilt binary does work and I seem to be able 
to use ifort in ncargf77 if I also include -lgfortran.   We are an ifort 
shop at NCEP.   The prebuilt binaries include idt.  One of our  fossil 
uses is to create 8 bit pixel xwd images with ictrans -D xwd.   This 
still works. Overall I think I have what I need for a functional NCL 6.1 
and have dusted off some rusty building skills in the process
Thanks for help.

The package(s) to install have names like "libcairo-devel", "libpixman-devel", "libfontconfig-devel", etc. It is very likely that once you install "libcairo-devel", the other packages will get installed automatically, so check for this before you install all the packages.
