I have /opt/swift in cepstral.conf in ld.conf.so.d.  It finds the 
library just fine on the command line and ldconfig -v gives me:

         libswift.so.5 -> libswift.so.5.1
         libceplang_en.so.5 -> libceplang_en.so.5.1
         libceplex_us.so.5 -> libceplex_us.so.5.1

It almost looks like Asterisk is not seeing the libraries for some 
reason.  I'm trying recompiling Asterisk now that Cepstral is installed 
to see if that helps.
