I installed Suite 2009 on a 64-bit Linux platform (Centos 5.4). When starting Maestro I get the error message:

/schrodinger/maestro-v90211/bin/Linux-x86/maestro: error while loading shared libraries: libGLU.so.1: cannot open shared object file: No such file or directory
Maestro: Could not load shared library

The program does not start. Is there a way around this problem?

This can happen if you install a 32-bit version of Maestro on a 64-bit machine. The 32-bit version requires certain 32-bit compatibility libraries to operate correctly on a 64-bit machine.

The missing libGLU.so.1 library is provided by the mesa-libGLU package.You will need to locate the appropriate RPM file on your installation media, and install the 32-bit package.

For example, on one of our CentOS 5 machines, the package is called: mesa-libGLU-6.5.1-7.5.el5.i386.rpm

Once you locate the file, you can install it with:

rpm -ivh mesa-libGLU-6.5.1-7.5.el5.i386.rpm

(Note: you will need to log in as root to do this).

You can also install it in one step with yum (as root):

yum install mesa-libGLU.i386 -y

It has been found that the following 32-bit packages have to be installed to make it possible for Maestro to run on 64-bit machines:

libXmu-1.0.2-5.i386
libXpm-3.5.5-3.i386
libXaw-1.0.2-8.1.i386
mesa-libGLU-6.5.1-7.7.el5.i386 -or- xorg-x11-drv-nvidia-libs.i586

Ensure that you have the 32-bit version installed in /usr/lib and the 64-bit version installed in /usr/lib64 before starting Maestro again.

Note the ".i386" part, which indicates that these are a 32-bit libraries and are different from ".x86_64" 64-bit packages.
