build fails if QTDIR= is set and libpng != 1.2.x

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Set environment variable QTDIR (e.g. QTDIR=/usr).
2. Run `build_mozc.py gyp'.

What is the expected output? What do you see instead?
Build fails due to the libpng12 is not found (build log attached).

In gui/qt_libraries.gypi, libraries file name is hard coded such as 'libpng12' 
and if installed libpng is not ver. 1.2.x, pkg-config fails.

What version of the product are you using? On what operating system?
Mozc-1.1.773.102
libpng 1.4.8
on Arch Linux (x86_64)

Thank you for the info.

Could you tell me if you can build and use Mozc by just removing libpng12 from 
the pkg-config list?
If everything is fine, we will just remove libpng12 from the list.

Works fine.
In my distro (Arch), libpng is depended on qt so it should be installed when 
installing mozc in either case (except with --no-qt).

Thank you for the info again.
libpng12 is removed from the list in our internal code tree. This change will 
be synced in the next code push.
