All right, I got the configure to finish without complaining. The
libltdl problem went away when I softlinked the libltdl.so.3.1.4 as
$HOME/local/lib64/libltdl.so . I didn't know that version number after
'so' matters for using
the '-l' flag.
 
No such luck with gc and unistring libraries which i had to download and
install separately. 

Thanks for all the pointers!
