ImportError when use macs2

[hanfeisun]

I use python setup.py install on a Ubuntu server.
However, when I run "macs2" in terminal.
It shows like this:

Traceback (most recent call last):
File "/usr/local/bin/macs2", line 35, in
from MACS2.OptValidator import opt_validate
File "/usr/local/lib/python2.6/dist-packages/MACS2/OptValidator.py", line 26, in
from MACS2.IO.cParser import BEDParser, ELANDResultParser, ELANDMultiParser, ELANDExportParser, SAMParser, BAMParser, BowtieParser, guess_parser
ImportError: /usr/local/lib/python2.6/dist-packages/MACS2/IO/cParser.so: undefined symbol: PyUnicodeUCS2_DecodeUTF8

I've installed numpy and cython in this server, but when I get into the directory of /usr/local/lib/python2.6/dist-packages/MACS2/IO. I found cFeatIO.so was not there. I get a copy from other server and put it here. But It didn't work.

Can you try to remove the old installation and the whole 'build' subdirectory in the source code directory, also all the .c files:

$ find MACS2/ -name '*.c' -delete

[hanfeisun]

I've deleted all the .c file ,the 'build' subdirectory and the old installationand,then run the setup.py again.

Cython (>=0.14.1) is required to run MACS v2. Can you check the version in your system?

[hanfeisun]

I see~ I install cython by apt-get, which is not the newest version.
I install a newer version and it's OK now.

I also have a problem similarly.< ImportError: No module named MACS2.Constants . > how can I solve it ?
