          I have downloaded the required files form site
			asterisk-1.2.24.tar.gz
 			libmfcr2-0.0.3-1.4.tar.bz2
 			libsupertone-0.0.2.tar.gz
 			libunicall-0.0.3-1.4.tar.bz2
 			spandsp-20060903.tar.gz

 	I downloaded and installed the files in the follwing sequence

	Can anybody tell me how to remove these errors

	I converted .src.rpm file of libmfcr2  to .deb file and installed it.
      I donot know wether is it is instal;led or not

Thanka and regards
