There never was a really good reason to support it.  The OpenPGP working group 
added TWOFISH as a 256-bit cipher (and not incidentally a 128-bit blocksize), 
and later AES.  There is nothing specifically wrong with CAST6, but given that 
OpenPGP has both TWOFISH and AES, there isn't really a pressing reason to 
include CAST6 too.
