Off the top of my head, reasons why I might not want to use NFS mounted extra libraries.

• Network latency. The dreaded slow NFS mount problem. Added program startup penalty.
• NFS mount goes away. Whoops. Now your program won't compile.
• Perhaps you don't want the exact same module version on every host.

    I concur with your point wrt library version - but, even so, differing versions can be mitigated for by having a base/stable version installed in the NFS mounted library and a different version installed locally to the machine as necessary - assuming a suitable PERL5LIB, perl on that machine will thus pick up the localised version in preference to the base/stable version.

    I infer from Network latency. The dreaded slow NFS mount problem... that you're only considering auto/soft mounts - a hard mount will remain for as long as the mount server is providing the resource &/or the network is up.

    From NFS mount goes away..., I take it that either your network &/or your mount server aren't as stable as most...

    Overall, it appears as though the local installation of libraries is the preferred, labour intensive work-round for network problems...

    A user level that continues to overstate my experience :-))
