    Hi,When I build the skyeye1.3.4 in ubuntu 11.10 and python2.7.2
    and when I run skyeye -e arm_hello,I have this error info:
    File "/usr/lib/python2.7/ctypes/__init__.py", line 10, in <module>
    from _ctypes import Union, Structure, Array
    ImportError: /usr/lib/python2.7/lib-dynload/_ctypes.so: undefined symbol: PyFloat_Type

    .I debug the codes,and I find it always occur at:

    SIM_init(){
    ....
    global_cli("SkyEye");------------ when execute this codes error occur.
    ...
    }

    I just change to ubuntu 10.10 with vmware. And I find it work well in it.And I find The python is 2.6 .But in ubuntu 11.10 the python is 2.7. Now I have not found the correct reason about what caused it.

    But now I can debug skyeye.And I have debug the skyeye_1_3_4_rel bug. And I have found it caused segmention error by a null handler:pmon_count_start(argp=0x0)

    I will furter debug this quetion.And find the root reason.
