app_conference

Hi all
I have problems compiling app_conference (I cannot use MettMe I need app_conference) I get the folowwing error:
gcc -pipe -Wall -Wmissing-prototypes -Wmissing-declarations -g -I/root/local/asterisk/asterisk/include -D_REENTRANT -D_GNU_SOURCE -O3 -ffast-math -funroll-all-loops -fprefetch-loop-arrays -fsingle-precision-constant -march=pentium3 -msse -mfpmath=sse,387 -DCRYPTO -DAPP_CONFERENCE_DEBUG -Ilibspeex -DSILDET=2 -c -o member.o member.c
member.c: In function member_exec': member.c:367: error: structure has no member namedcid’
member.c:367: error: structure has no member named cid' member.c:367: error: structure has no member namedcid’
make: *** [member.o] Error 1

Does anybody know how to fix that ???
Thank you in advance
