[Freeswitch-users] weird bootstrap error

Got a wierd error (i think) running bootstrap.sh. It stop at the following line and did not return to the linus prompt. /usr/src/freeswitch# automake: compiling `check_dlopen_sofia.c' with per-target flags requires `AM_PROG_CC_C_O' in `configure.ac' tests/Makefile.am:37: while processing program `check_dlopen_sofia' Is this normal?
