Hi I have resolved the Installation errors. for mod_perl one needs to install mod_perl-devel (thanks Mike). and for soundtouch, install soundtouch from sourgeforge. I have enabled module asr_tts/mod_flite and asr_tts/mod_pocketshinx but after installation, I haven't found the directory mrcp_profiles. My modules.conf is located at /usr/src/freeswitch-1.0.4pre5 Why there is no mrcp_profiles directory created after installation. Regards Vin
