Does the /home/spiral2mgr/APPLICATIONS/PERL/cap5-0.1/lib/<host-arch> directory 
contain the file libCap5.so?  The thing it can't find (or load, see below) is 
the shared library (the "loadable object") containing the compiled part of 
the interface.

Confusingly the tarfile is not in the extensions area but in the modules 
download area instead:
	http://www.aps.anl.gov/epics/download/modules/index.php
The latest release available there is version 0.3, with a newer version 
included in Base R3.14.10.

I think the problem is the shared-library dependencies that it can't find, 
i.e. libCa.so and libCom.so.  If you moved Base at the same time you will 
have to recompile ("make rebuild") the cap5 module because it burns the path 
to the base/lib/<host-arch> directory into the libCap5.so file.

HTH,
