libetpan @1.9.1: error: duplicate case value 'CURLE_PEER_FAILED_VERIFICATION'

[kencu (Ken)]

libetpan built fairly recently, but no longer builds for me. I presume some update to curl had caused it to fail now:

libtool: compile:  /opt/local/bin/clang-mp-3.9 -DHAVE_CONFIG_H -I. -I../../.. -I../../../include -I../../../src/data-types -I../../../src/low-level/imf -I/opt/local/include -DDEBUG -I/opt/local/include -D_REENTRANT -I/opt/local/include -I/opt/local/include -pipe -Os -arch x86_64 -W -Wall -c newsfeed_item.c -o newsfeed_item.o >/dev/null 2>&1

make[7]: *** [newsfeed.lo] Error 1

we still have the current version on the buildbots, it appears, presumably built against some previous curl.
