gracias! ha sido leer la primera pagina del manual y ver la solucion, yo me
quejo de los usuarios y no me aplico la fantastica regla del RTFM,
Seguiré investigando :)

Sí. Sugiero leer el manual de PNGwriter, donde está especificado cómo
compilar, qué librerías necesitas (Freetype2 opcional, libpng, libz) y
ese tipo de detalles.
Te recomiendo leer los makefiles de los programas de ejemplo que trae
PNGwriter. Si lo instalaste vía un package manager y no encuentras los
programas de ejemplo, mejor baja PNGwriter directamente de
sf.net/projects/pngwriter, compílalo según las instrucciones, pero no
lo instales.
Suerte y cuéntanos cómo te va.
