>Description:
When the bundled version of perl is compiled and installed with
PERL_THREADED=yes, it improperly sets the libs variable in
/usr/libdata/perl/5.00503/[mach/]Config.pm to '-lm -lc -lcrypt'
instead of '-lm -lc_r -lcrypt'.  This causes programs linked
against libperl to also link both libc and libc_r; which (usually)
causes a BUSERR in exit().

>How-To-Repeat:
Set PERL_THREADED=yes.
make world
reboot
build exim 2.0 with perl enabled.
ldd exim
You will see both libc and libc_r in the libraries list.
>Fix:
Modify the bundled perl build to correct the value of libs in
Config.pm when PERL_THREADED is specified.
