>Description:
   lang/perl fails to compile with this message:

   Which of these apply, if any? [freebsd]  

   Some users have reported that Configure halts when testing for
   the O_NONBLOCK symbol with a syntax error.  This is apparently a
   sh error.  Rerunning Configure with ksh apparently fixes the
   problem.  Try
        ksh Configure [your options]

   Operating system name? [freebsd]  
   Operating system version? [8.0-rc2]  
   Installation prefix to use? (~name ok) [/usr/pkg]  
   AFS does not seem to be running...
   What installation prefix should I use for installing files? (~name ok)
   [/usr/pkg]  
   Build Perl for SOCKS? [n]  
   Use the PerlIO abstraction layer? [y]  
   Getting the current patchlevel...
   Build a threading Perl? [y]  
   POSIX threads should be supported by FreeBSD 8.0-rc2 --
   but your system is missing the shared libc_r.
   (/sbin/ldconfig -r doesn't find any).

>How-To-Repeat:
        cd /usr/pkgsrc/lang/perl5; bmake
