Missing bnf functions

[Malcolm Bovey <malcolm.bovey@gmail.com>]

Hello all,

I'm having trouble running some code on a Mac OS X (v 10.6.8) installation.   I downloaded and compiled the latest stable version of PARI-GP (2.5.1) - this seemed to be successful.  However, PARI doesn't seem to know about some internal functions that it should do.  For example, when I try using bnfclassunit, I get

bnfclassunit(x^2-5)
  ***   at top-level: bnfclassunit(x^2-5)
  ***                 ^-------------------
  ***   not a function in function call
  ***   Break loop: type 'break' to go back to GP

bnfinit seems to work fine.

Any suggestions as to what's going wrong here?

Thanks
Malcolm
