The error you showed previously was for libpng.a; this error is for libz.a. Probably \
similar though. It looks like Perl-Tk has an included copy of zlib, libpng and jpeg \
that it will build if it cannot find one on your system. And it looks like you (or \
the build system) requested the build happen for three architectures: x86_64, i386 \
and ppc. And the build system does not support fat libraries, because it tries to run \
"ar rc" on them, which you can't run on fat files. You would need to change the \
Makefile to run "ar rcs" instead, I think. But it would be better to use separate \
up-to-date zlib, libpng, and jpeg libraries, such as the ones provided by MacPorts. \
And then it would be better to use the p5-tk port since it already knows how to do \
that.

In MacPorts, I'm able to build p5-tk, unless I deactivate my zlib, libpng and jpeg \
ports, in which case I get an error when trying to build the included libpng. A \
different error, but also related to using multiple -arch flags. So p5-tk needs \
dependencies on those ports, which I have now added:

As a rule, I prefer to install software with MacPorts, since it means someone else \
has already figured out the details of how to do that on Mac OS X and I wouldn't for \
example generally run into surprises like the ones you're now running into. However, \
I have no idea how tlmgr works, or how it finds its perl binary or modules. If \
possible, you would need to tell tlmgr to use the perl installed by MacPorts in \
/opt/local/bin/perl, or add MacPorts perl's module paths to the perl that tlmgr uses.
