Hi!

Following the instructions below and attaching the requested files.

Thanks :-)

---------------------------------------

checking for png_get_acTL in -lpng... no
configure: error: --with-system-png won't work because the system's 
libpng doesn't have APNG support
===>  Script "../configure" failed unexpectedly.
Please report the problem to gecko@FreeBSD.org [maintainer] and attach the
"/usr/ports/www/firefox/work/mozilla-release/obj-i386-portbld-freebsd9.1/config.log"
including the output of the failure of your make command. Also, it might be
a good idea to provide an overview of all packages installed on your system
(e.g. a /usr/sbin/pkg_info -Ea).
*** [do-configure] Error code 1

*** [build] Error code 1
