I tried to install Tk-804.028_501 on Mac OS X 10.6 (Snow Leopard) 64bit. But the "make test" gives me this:

dyld: lazy symbol binding failed: Symbol not found: _png_create_write_struct
Referenced from: /User/k/perl/Tk-804.028_501/blib/arch/auto/Tk/PNG/PNG.bundle
Expected in: flat namespace

And I cannot open PNG image files in Perl/Tk windows. Perl gives me the same error message and exits.

I installed libpng separately and run the make sequence of Perl/Tk again. But no luck so far.

Any help or hints?

Thanks and sorry for my poor English.
