asterisk users - Aug 2007 - error in linking libmfcr2

hi,
   I am using debian 4.0 with version 2.6.18-4-686
          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
	spandsp
	libsupertone
	libunicall
		Till here it is compiling and copying .so library to /usr/local/lib/

     libmfcr2-0.0.3 source code by doing some modifications compiled
correctly
     but while linking it is giving error  "libtool: link: only absolute
run
ptahs are allowed."
     when running make command
     Can anybody tell me how to overcome this error
Thanks and regards
sanchal
