 Ok, I found the source, (it doesn't appear to be Ruby's
 fault) but it's not clear to me how to correct it. 
 I have wrapper csh script that calls exec 
 on ruby. Exec is supposed to redirect stdio. Since I get
 the version to print it appears to be working for stderr,
 but not for stdout.

 % -> ruby.wrap -e 'puts $:.join("\n")'

 -> ./ruby.wrap -v
 ruby 1.7.3 (2002-12-04) [i386-freebsd4.6]
 % -> cat ruby.wrap 
 #! /bin/csh -f
 exec /home/jfreeze/ruby173/bin/ruby $argv[*]

Anyone know how to fix this?
Thanks
