Comment (by hsn):

 i deinstalled libevent1 from freebsd to make situation more clear.

 configure script is looking first for <event.h> not for <event2/event.h>.
 There is no <event.h> in freebsd libevent2 installation.

 `configure:6634: gcc -c -g -O2 -I/usr/local/lib/event2
 -I/usr/local/include -I${top_srcdir}/src/common conftest.c
 >&5conftest.c:56:19: error: event.h: No such file`

 checking for event2/event.h starts in configure.ac at line 443 but it
 never gets there because it fails earlier. Maybe reorder these checks?
