I have an error to compile the latest version of python2-biggles on 
Cygwin/WindowsXP.
I would appreciate if someone would help me to build biggles.
I paste the error message at the bottom. 
The message says that the undefined reference "_png_*" in ibrary libplot.a

I have downloaded and made
zlib-1,2,1.tar.gz
libpng-1.25.tar.gz
plotutils-2.4.1.tar.gz
Numeric-23.1.tar.gz

The libplot.a was built in ~/plotutils-2.4.1/libplot
When I created libplot.a in plotutils there was an warning,
/plotutils-2.4.1/libplot
libtool: link: warning: undefined symbols not allowed in i686-pc-cygwin
