Resolution:
On Solaris you may see error messages in /var/adm/message that the automounter can not load or access /home/fiedler/opt/SUNWspro/lib/rw7/libsocket.so.1.  This is the default location the loader looks for libsocket.so.1 because that was where the compiler found the library.  This lib is usually found in /usr/lib so specify /usr/lib in LD_LIBRARY_PATH will
solve this issue on either Solaris or Linux.  On HPUX you will need to set SHLIB_PATH and on AIX it will be LIBPATH.

Adding /usr/lib to the library path as specified above will also fix the problem with the installation hanging.

You can use ldd on Solaris or Linux on IcServer or IcRepDeamon to find any libs that it tries to find in the default location of show  /home/fieder.  Those libs must be found in the local system directories.  Once found locally the library path then needs to be updated.

If fixing the library path does not fix the problem then look for automounter problems.  A reboot may fix the problem.
