[ncl-install] [ncl-talk] error while loading shared libraries: libbz2.so.1: cannot open shared object file:

Dave,

On Linux systems, it's better to use package managers like "yum" or
"apt-get" to install packages.

Please see:

http://www.ncl.ucar.edu/Download/linux.shtml#InstallSoftware

You should be able to do something like:

yum install libbz2-dev

or

apt-get install libbz2-dev

I have a feeling that your system is not seeing the bz2 libraries in
/lib64, because it looks like you have a 32-bit system (you downloaded a
32-bit binary for NCL).

If you use a package manager, then it will put the libraries in the correct
place on your system.

Please verify that you have a 32-bit system, however:

uname -a

If this reports "x86_64", then you have a 64-bit system, and you should be
installing a 64-bit version of NCL and not a 32-bit version.

--Mary
