povray @3.6.1_7 Build failure

[murrayeisenberg@…]

OS X 10.8.1, Xcode 4.4.1 with corresponding command-line tools.

After doing 'port selfupdate' I ran 'port upgrade outdated'. The latter aborted after:

--->  Attempting to fetch povray-3.6.1_7.darwin_12.x86_64.tbz2 from http://lil.fr.packages.macports.org/povray

Error: org.macports.build for port povray returned: command execution failed
Please see the log file for port povray for details:

Error: Unable to upgrade port: 1
}}}}


In the log, aside from many "deprecated" warnings, the first error listed is:

{{{{:info:build png_pov.cpp:170:19: error: member access into incomplete type 'png_struct' (aka 'png_struct_def')
:info:build           longjmp(png_ptr->jmpbuf,1);
:info:build     }}}}                     ^


There were numerous other errors of the same kind. 

In response to a message I posted to macports-users@lists.macosforge.org, Jeremy Lavergne <jeremy@lavergne.gotdns.org> replied, "That's due to the libpng API change recently; we'll need to update all the packages affected."
