w3m raises the following error:

istream.h:23:8: error: redefinition of 'struct file_handle'

I found the needed patch [1].  But I don't want to apply it because it
requires a knowledge of C.  Could anyone help me to finalize the recipe?

Also, I'm not sure what license should be used.  Should we create a new
one?

This page [2] states that w3m is under MIT, which is an ambiguous name
of the Expat License [3].  However, the License paragraph in
'doc/README' doesn't look like Expat.
