question on before building

can someone explain this to me:

After downloading and extracting the source but prior to performing the
build apply the bug fix patches in the libwww directory of the OpenVXI
package by merely replacing the files in the libwww distribution with the
files in that directory (the paths and file names are identical).

it looks like i will need to find a directory called libwww distribution,
and then i will need to use the file within libwww (which would be from
Library/src) to replace the files in the directory of libwww distribution.

but i can't find the libwww distribution.  am i misunderstanding here?

please help.  Thanks!
