Pango 1.9.1 problemo building on Mac OS X 10.4

[Ryan Schmidt <gtk-2005 ryandesign com>]

Hi there. Hope this isn't a FAQ, or I'll feel silly. I'd so much like  
to compile Pango 1.9.1 on Mac OS X 10.4.2, it just won't go for me. I  
like to think that I know how to install software, but then the  
compiler screams at me and I have to run crying to the mailing list  
to kiss it and make it better.

The real goal here is to have Graphviz 2.4 generating antialiased  
graphs using the new Graphviz Cairo plugin. This has led me through a  
bunch of dependencies, and I'm installing all of it in $HOME/graphviz  
for the moment. So far I've got Graphviz 2.4, libpixman 0.1.6, Cairo  
0.6.0, GLib 2.7.6 and ATK 1.9.0 compiled and installed in there.  
Where I'm stuck is that the Graphviz Cairo plugin needs GTK+, which  
needs Pango, which is throwing a fit.

I should also mention that I have DarwinPorts installed, hopefully  
fulfilling some remaining dependencies, like gettext. I'd install  
everything with DarwinPorts if I could, only these fresh versions  
aren't yet available there.

To set up the build environment, I took an example from the section  
"How do I compile something myself using Fink-installed software?" here:

http://fink.sourceforge.net/faq/usage-general.php

And I adapted it, changing from Fink's /sw to DarwinPorts' /opt/local:

export CFLAGS="-I/opt/local/include -I$HOME/graphviz/include"
export LDFLAGS="-L/opt/local/lib -L$HOME/graphviz/lib"
export CXXFLAGS=$CFLAGS
export CPPFLAGS=$CXXFLAGS
export ACLOCAL_FLAGS="-I/opt/local/share/aclocal -I$HOME/graphviz/ 
share/aclocal"
export PKG_CONFIG_PATH="/opt/local/lib/pkgconfig:$HOME/graphviz/lib/ 
pkgconfig"
export PATH="$HOME/graphviz/bin:$PATH"

I hope I got all that right. Then, in the pango-1.9.1 directory, I  
did this:

./configure --prefix=$HOME/graphviz
make

The stderr output of "make" is lots of this:

powerpc-apple-darwin8-gcc-4.0.0: unrecognized option '-pthreads'

and also this:

I'm hoping that the _locale_charset errors in my iconv and gettext  
DarwinPorts are not fatal, since they're shown multiple times. The  
___moddi3 problem looks somehow more ominous, as it's in libraries  
that were provided by Apple.

Anyone see anything they recognize? I'd appreciate any suggestions or  
pointers.
