you could just test locally.  if it works there it works.  what i mean is,
it's beyond the scope of the extension to know if the actual kernel code
works when applied to an nfs filesystem vs. a local one - it just makes the
call to fcntl and trusts that the impl works.

here's something you could try:

   require 'posixlock'
   def lock_test
     pid = Process.pid
     42.times do
       open(__FILE__,'r+'){|f| f.posixlock(File::LOCK_EX) and puts "locked by <#{ pid }>"}
     end
   end
   fork ? lock_test && Process.wait : lock_test


thanks VERY much for checking that out!!!  i'll start a list of known
successful compiles - can you give me anymore info?  versions, win platform,
etc.?

kind regards.
