In the past I have had numerous problems attempting project builds over network mounts. I've not tried with Racket specifically, but I have had difficulties with various C(++) toolchains. NFS had a lot of issues for a long time, but it did get noticeably better with v4. If you're not using 4 you should try to get the powers that be to upgrade. However ... WRT Racket on Centos: I compiled Racket 6.1.1 (full) onto Centos 6.6 and am running it with no problems - however all storage is local. I do have root access, but it isn't needed: private install works fine. I have a private install on a GUI desktop system and a root command line install on a headless server. I haven't tried installing xrepl myself, but I do have several other packages installed over the main distribution. Again no problems. I did see the message from John Clements. I'm not a Racket developer, but superficially it appears to me that the negative delay values John found should be causing errors on every platform that supports file locking [which is every supported platform]. Clearly they aren't, so now I am wondering whether locking actually is enabled and being used for local filesystems. Sorry I can't be much help. Just speculation.
