Problem compiling on x86_64 using Gentoo

[GoogleCodeExporter]

After installing version 0.2-r1 using the experimental ebuild for Gentoo I
found out that the V4L API might be broken (explaining the blank training
windows) and that I should upgrade to 0.3.

After grabbing the latest revision from SVN, I run autogen.sh:
/usr/bin/gnome-autogen.sh

**Warning**: I am going to run `configure' with no arguments.

`./autogen.sh' command line.

What this output hides is the message from automake that it will not write
Makefile.in because of the errors.

I tried the suggestions from the autogen.sh script to get rid of the
warnings and wind up with a Makefile.in but the resulting Makefile has
errors in it preventing me to compile it properly.

Sonce others don't seem to have issues compiling the SVN version, what is
going wrong on my PC?

What steps will reproduce the problem?
1.
2.
3.

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Please provide any additional information below.
