Sigh.

The only change between the first revision of 2.0.5 (r101233) and the current revision (r102174) is a revision bump and compiler choice changes:

It looks like you're falling back on /opt/local/bin/gcc-apple-4.0 to build ...

Leaving open to remind me to revert after base 2.2 is out.

Replying to jeremyhu@…:

My apologies, but it seems I did not provide you with all relevant information when filing this ticket.
I only realized this after seeing your comment on the compiler choice changes.
I failed to mention that on top of latest VLC Portfile I run a patch to enable the use of clang 3.1 instead of version 3.0.
The patch with additional changes has been attached to this ticket for your inspection.

[jeremyhu (Jeremy Huddleston Sequoia)]

With the new blacklisting, you should be able to set those preferences yourself (at your own risk) by setting default_compilers in macports.conf. For example, if you don't like the current options for Leopard:

{gcc-4.2 apple-gcc-4.2 gcc-4.0 macports-clang-3.2}

You can add this to /opt/local/etc/macports/macports.conf to prefer clang:

default_compilers macports-clang-3.2 apple-gcc-4.2 gcc-4.2 gcc-4.0

Note that many ports just check for "clang" rather than all the options, and this feature is a "developer" feature which is not recommended unless you like finding and fixing all the problems it uncovers ;)

Thank you for the tip, I'll try using this feature.
