Hi!
The vigra library included in hugin-2010.0.0 doesn't compile against
png-1.4.2.
It uses the png_set_gray_1_2_4_to_8() function that was deprecated in
png-1.0.18 (2004) and png-1.2.9 (2006) and removed in png-1.4.0. The
official porting instructions at
http://www.libpng.org/pub/png/src/libpng-1.2.x-to-1.4.x-summary.txt
recommend replacing it with png_set_expand_gray_1_2_4_to_8().
Here's a patch:

png_set_expand_gray_1_2_4_to_8(): ").c_str());
+ png_set_expand_gray_1_2_4_to_8(png);
bit_depth = 8;
}
Please include it in the next release, thanks.
