png 1.2.7 is 6 years old and buggy! The function was called
png_set_gray_1_2_4_to_8 back then.

We should require a particular libpng version in configure.

I see libavcodec and libboostthread are the two libraries you've put in
another place. 

make V=1 will show you the actual compiler and linker commands instead
of "CXXLD", which might help you to check why those libraries aren't
being linked correctly.
