Problem with libraries

[dark0s Optik]

I have the following four problems:

1)

#acroread
(acroread:818): Pango-WARNING **: No Builtin or dynamically loaded
modules were found. Pango will not work correctly. This probably means
there was an error in the creation of:

    /etc/opt/gnome/pango/pango.modules
You may be able to recreate this file by runnning pango-querymodules

(acroread:818): Pango-CRITICAL **: _pango_engine_shape_shape:
assertion PANGO_IS_FONT

Pango-ERROR **: file shape.c: line75....

2)

#xine
/usr/libexec/ld-elf.so.2: Shared object libpng12.so.0.23.0 not found,
required by xine

3)

#mplayer
/usr/libexec/ld-elf.so.2: Shared object libSDL-1.2.so.0.11.1 not
found, required by mplayer

4)

I have installed firefox-2.0.0.13.tgz and firefox-bin-2.0.0.13.tgz,
but when I type, I do not have output

#firefox
#

How can I solve above four problems?


Thanks
