The X11 SDK needs to be installed from the XTools CD. It seems that
after the installation, the X11 include files are at a unusal
location. If so, then start installation by specifying the X11INC
variable, i.e.

    perl Makefile.PL X11INC=/Developer/SDKs/MacOSX10.4u.sdk/usr/X11R6/include

This was seen on a Mac OS X 10.4.8 (Tiger) system.

It is expected that make test passes without failures.

Turning on True Type support with XFT=1 also seems to work, but there
are some font metrics-related test failures, which are
harmless:

Older notes:

For Tk804.025 to build properly on Mac OS X 10.2 (Jaguar) or 10.3
(Panther), Perl must be built dynamic, rather that the default of
static.  Use a Configure incantation similar to this:

sh Configure -des -Duseshrplib [-Dprefix=/path/to/your/private/perl]

Be sure you install the X11 SDK from the XTools developer CD - this
installs the X11 C headers files, else the make will fail:

    I installed the latest X11 from Apple, but the latest TK804 beta
    gives me the following:

    Using -L/usr/X11R6/lib to find /usr/X11R6/lib/libX11.dylib
    Cannot find X include files via /usr/X11R6/include
    Cannot find X include files anywhere at ./myConfig line 332.
    Compilation failed in require at Makefile.PL line 32.
    BEGIN failed--compilation aborted at Makefile.PL line 34.

On my Panther (10.3.2) system, it can be found in:
    
    Applications->Installers->Developer Tools->Packages.
