Your Squid executable is not linked with libecap, resulting in undefined
references to libecap symbols:

I am not sure why Your Squid executable is not linked with libecap, but
I suspect that manually setting EXT_LIBECAP_CFLAGS and EXT_LIBECAP_LIBS
confuses ./configure. You should not set those variables manually and
let Squid compute them automatically instead. You may need to set
PKG_CONFIG_PATH if Squid cannot find libecap.pc without it.


HTH,

Alex.
P.S. I assume you meant to type "3.5.20" in the Subject
