On Debian/unstable, I get:

Type ? for help, \q to quit.
Type ?12 for how to get moral (and possibly technical) support.

parisize = 8000000, primelimit = 500000

  ***   not a function in function call
A function with that name existed in GP-1.39.15; to run in backward 
compatibility mode, type "default(compatible,3)", or set "compatible = 3" in 
your GPRC file.

New syntax: ln(x) ===> log(x)

log(x): natural logarithm of x.
