No - I was just looking for a way to make ActivePerl work 'out of the
box' - I'm sure the defaults should be as you have them. On further
thinking about this, I think the ActivePerl / gcc-4.0 / 10.4 dependency
is just one particular different case - all of which can be dealt with
using the wxWidgets-extraflags option noted below.
Re wxWidgets-extraflags option
Looks useful: could you add it?
I've committed the wxWidgets-extraflags option to svn.
For reference for the list, on unices and osx use wxWidgets-extraflags
to pass extra arguments to ./configure. You can include anything
mentioned by ./configure --help
On MSWin makefile builds wxWidgets-extraflags can contain the make
options as defined in build/msw/config.gcc etc.
For example, I want a unicode build using wxGraphicsContext and I want
Alien-wxWidgets to download and build wxWidgets 2.8.10 for me without
intervention:
Unices
perl Build.PL --wxWidgets-build='yes' --wxWidgets-source='tar.gz'
--wxWidgets-unicode=1 --wxWidgets-version=2.8.10
--wxWidgets-extraflags="-enable-graphics_ctx"
OSX
perl Build.PL --wxWidgets-build='yes' --wxWidgets-source='tar.gz'
--wxWidgets-unicode=1 --wxWidgets-version=2.8.10 --wxWidgets-universal
--wxWidgets-extraflags="-enable-graphics_ctx"
MSWin
perl Build.PL --wxWidgets-source=tar.gz --wxWidgets-unicode=1
--wxWidgets-mslu=0 --wxWidgets-version=2.8.10 wxWidgets-unicode=1
wxWidgets-extraflags="USE_GDIPLUS=1"
(note, for MSWin build USE_GDIPLUS will fail unless you have appropriate
platform SDK installed)
Re ExtUtils:FakeConfig / -nostdinc
I do not see a better way. It's a pity that -nostding is both used by
ActivePerl and suggested in the OS X Perl README.
Attached is Config_osx.pm that maybe could be added to ExtUtils::FakeConfig
For reference for the list, primary use is to remove '-nostdinc' from
appropriate Config entries and allow Wx to build with new exception
handling and ExtUtils::XSpp > 0.6. It will also specify gcc-4.0 if you
are using ActivePerl.
For a little more completeness, I added the capability of setting
architectures via an environment variable. (as use of this module might
prevent use of Config_u)
Of course the possible architectures you get for wxPerl are set when you
build wxWidgets.
Simple usage
perl -MConfig_osx Makefile.PL
will just allow you to build Wx if your Perl Config includes
'-nostdinc', and will additionally set the gcc version if you are using
ActivePerl.

__DATA__
=head1 NAME
Config_osx - compile Mac OS X modules without '-nostdinc' flag
=head1 SYNOPSIS
perl -MConfig_osx Makefile.PL
make
make test
make install
with CPAN.pm/CPANPLUS.pm
set PERL5OPT=-MConfig_osx
cpanp
=head1 DESCRIPTION
This module is only useful at Makefile.PL invocation time. It modifies
some %Config values allowing compilation of Perl XS modules without passing
the '-nostdinc' flag. For current versions of ActivePerl, will also set
the required compiler version (gcc-4.0).
You may override the -nostdinc exclusion by setting environment variable
export FAKECONFIG_USE_NOSTDINC=1
The module also allows you to specify which architectures should be built
by setting the environment variable FAKECONFIG_USE_ARCHITECTURES.
Allowed architectures are ppc, i386, x86_64
For example, to specify universal 32 bit binaries
export FAKECONFIG_USE_ARCHITECTURES="i386 ppc"
to specify combined 32 and 64bit intel binaries
export FAKECONFIG_USE_ARCHITECTURES="i386 x86_64"
