Without having dev-python/mako installed, building media-libs/mesa-9999 will fail like this: checking how to hardcode library paths into programs... immediate checking for bison... bison -y checking if bison is the parser generator... yes checking for flex... flex checking lex output file root... lex.yy checking lex library... -lfl checking whether yytext is a pointer... yes checking if flex is the lexer generator... yes checking for indent... cat checking if module mako in python is installed... No module named mako configure: error: mako 0.7.3 or later is required.
