error configure doubango srtp_create in -lsrtp... no

[etelts]

I'm trying to compile the latest version of doubango with so many difficulties.
Now I encounter this error when give the command ./configure --with-ssl --with-srtp --with-speexdsp

checking srtp/srtp.h usability... yes checking srtp/srtp.h presence... yes checking for srtp/srtp.h... yes checking for srtp_create in -lsrtp... no configure: error: You requested SRTP (requires libsrtp) but not found...die

I have compiled libsrtp whithout --enable-pic because I get always the error that say me that --enable-pic is an unknow option (I have execute runtest at the and of compilation an it passes).
There are someone that can help me ?
Thank in advance,
Emilio

SOLVED download and compiling NOT LATEST version of libsrtp but the 1_5_x version.

New error in ./configure of doubango using --with-speexdsp (speex and speex-dev is installed by apt).
Not solved also getting source code of speex and compiling it as in technical guide.

Fortunately it seems that opus substitute speex (I am not sure !).

./configure with option --with-opus and without --with-speexdsp and with congratulation !

New error in make file: in line 909 is missing a tab (this block execution of make).

Fortunately this is easy solved.

New errors compiling doubango:
