[squid-users] Patching stable10 enable icap?

I am having problems applying the icap patch to stable10 using:

patch -p1 <../patchfile

I get the below error:

linux:~/software/squid-2.5.STABLE10 # patch -p1 < ./icap-2.5.patch
patching file acconfig.h
patching file configure.in
Hunk #1 succeeded at 464 (offset 22 lines).

Hunk #3 succeeded at 1908 with fuzz 1 (offset 44 lines).

Perhaps you used the wrong -p or --strip option?
