Compiling Pl/Perl on Mac OSX

Hello all,

Has anyone had any luck compiling the Pl/Perl language on Mac OSX
(10.4)? I get the following error:

*** Cannot build PL/Perl because libperl is not a shared library.
*** You might have to rebuild your Perl installation. Refer to
*** the documentation for details.

If I modify Makefile.global and set "perl_useshrplib = true" I get
the linker error:

gcc -no-cpp-precomp -O2 -Wall -Wmissing-prototypes -Wpointer-arith -
Winline -Wdeclaration-after-statement -Wendif-labels -fno-strict-

Not super surprising, of course, but if I look for libperl, I find:

/System/Library/Perl/5.8.6/darwin-thread-multi-2level/CORE/libperl.dylib
/System/Library/Perl/lib/5.8/libperl.dylib

Which seems like it should fit the bill. I can't seem to find any
docs online that say one way or another how I can make this work.
Any thoughts? Thanks!
