install cmake problem OS X 10.10

[ypeysson@…]

Hi, I try to install cmake, in a clean way from macport. I have the last Xcode 6.1 downloaded from Apple Store, and the correct sdks. It seems to compile fine, but I face a problem in the test phase that prevent the correct installation:

/bin/ps: Operation not permitted

It seems to be an already seen problem in macport, but clearly not fixed.
What can you do, or can I do ?
Thanks
Yves
