I am trying to do the following on RedHat RHEL 5.0:

I think you can pass Nothing instead of a Just, since that argument is ignored when opening read only. If you feel you need to pass something, use nullFileMode. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
