Thomas,
Sorry it took me awhile to respond - I'd left things compiling when I
went home last night, and it failed, so I had to fix it and get it going
again this morning. With libpng 1.5.3 beta3 and mapserver 6.0 beta 7
(since it was released before I fixed things this morning), everything
now seems fine.

Christy,
Can you confirm that the bug disappeared with the latest libpng beta ?

Aha, thanks Thomas. I hadn't found that.

Christy,
I suspect this is due to a bug in libpng. see

Hi,
I compiled MapServer 6.0 beta6 against libpng 1.5.2 and encountered the
following problems:
when using the default png IMAGETYPE (i.e. no OUTPUTFORMAT block), I got
yellow& striped maps (see cyprus.png)
when using the AGG/PNG driver and IMAGEMODE "RGBA", the output image
looks
fine
when using the default png8 IMAGETYPE, the output image looks fine
I also compiled with cairo, and with the driver set to CAIRO/PNG, I had
the
same yellow& striped maps.
rgba and png8 use different png formats. agg/png and cairo/png use the
same codepath when saving images, so the behavior your are observing
is normal.
With libpng 1.2.44, everything seems to work properly. Has anyone else
seen
this problem with libpng 1.5? Should it work properly with MapServer?
Regards,
Christy
