ettercap can't cross compile as acinclude.m4 use AC_TRY_RUN to determine if NS_GET32 exist.

Created attachment 280411 [details, diff] ettercap-0.7.3-r4.ebuild-BJA-autotools.diff Previous patch impose to run twice autoconf, I really don't understand why, so it's a bit crap but actully work. Also add --with-libnet to precise libnet PATH.

Could you test latest 0.7.5_pre* ? It is based on cmake and should not fail.

(In reply to comment #1) changing to TRY_LINK from TRY_RUN for NS_GET32 is fine ... we just want to make sure the macro exists and expands correctly (a compile would miss the case where it didn't exist and so becomes an undefined func reference). EC_GCC_MACRO could be a compile-only test, but the current logic doesn't do anything useful other than error out when doing a native test (skips for cross). (In reply to comment #2) ROOT should never be used in a src_* func, so this change is unacceptable. the autotool logic also looks completely broken. libnet doesn't provide a .pc file, just a -config script, so you probably want to use the `cross-fix-root` script to mung things to work for cross-compiling.
@Bertrand Jacquin please attach you emerge --info
(In reply to comment #5) > But it fail ;) Please test latest tarball: ettercap-0.7.5_pre20121006
Somebody should get libnet upstream to provide a .pc
