seems the custom AC_LBL_C_INIT macro libpcap ships with pisses off autoconf and in general, looks like a behind-the-back-hack. $ autoconf configure.in:24: warning: AC_REQUIRE: `AC_PROG_CC' was expanded before it was required ../../lib/autoconf/c.m4:433: AC_LANG_COMPILER(C) is expanded from... ../../lib/autoconf/lang.m4:315: AC_LANG_COMPILER_REQUIRE is expanded from... ../../lib/autoconf/general.m4:2593: AC_COMPILE_IFELSE is expanded from... ../../lib/autoconf/general.m4:2601: AC_TRY_COMPILE is expanded from... aclocal.m4:45: AC_LBL_C_INIT is expanded from... configure.in:24: the top level $ ./configure checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking target system type... x86_64-unknown-linux-gnu ./configure: line 2455: syntax error near unexpected token `newline' ./configure: line 2455: `yes:' if we edit aclocal.m4 and change AC_LBL_C_INIT: - AC_BEFORE([$0], [AC_PROG_CC]) + AC_REQUIRE([AC_PROG_CC]) then it seems to "work", but i dont know how this affects this macro

I agree with Mike's patch, that seems to do what they tried to do in the first place.
http://www.gnu.org/software/hello/manual/autoconf/Expanded-Before-Required.html
that doesnt really help. we know why the code doesnt work, but we dont know what upstream actually wanted to do.
ive changed the code to AC_REQUIRE for now as it's largely superfluous http://sources.gentoo.org/net-libs/libpcap/libpcap-1.0.1_pre20090812.ebuild?r1=1.1&r2=1.2 http://sources.gentoo.org/net-libs/libpcap/files/libpcap-1.0.1-autoconf.patch?rev=1.1
This was fixed by upstream in libpcap-1.1.0.
*** Bug 313103 has been marked as a duplicate of this bug. ***
Can we please get a version that builds with the soon-to-be-stable autoconf stable?
