Thank you for the fast Help

I hope its OK if I use English here.
Most of the sites I already knew. (unfortunately)
I tried this example from here.
http://gmaths.free.fr/asymptote//Change ... rabole.asy
Unfortunately there occur an error!
asy responds whit the following prompt:
"
/usr/share/asymptote/base_pi.asy: 426.25: cannot call
'transform rotate(real angle, pair z=<default>)'
with parameter '(pair)'
"
My actual asy version is:
Asymptote version 2.15 [(C) 2004 Andy Hammerlindl, John C. Bowman, Tom Prince]
Compile Version of the sample code were 1.95
AN examples from version 2.14 work!
How can I fix the problem to use all the examples
I also put the following additional modules in my asymptote directory, but I am not sure if there are some missing ones.
garph_pi.asy
base_pi.asy
geomertry_dev.asy
