I upgraded from 4.1 to 4.2 with X and upgraded gnash. Now when I go to

certain sites using Firefox I get the following in STDOUT -
/usr/local/bin/gnash: can't load library 'libavcodec.so.8.0'

/usr/local/bin/gnash: can't load library '/usr/local/lib/libcurl.so.5.0'

Child process exited with status 1024
Starting process: /usr/local/bin/gnash -v -x 8427142 -j 100 -k 100 -u

Could anyone shed some light on this and how to resolve this issue?
Thanks for any help.
