[yt-users] yt install error on Mac

[Junhwan Choi (최준환)]

Hi yt users,

Recently, I try to install the yt on my mac desktop that uses OS X 10.8.4.
While installing yt, I face on strange error and fail to insall.
........
    self._load()
  File "/Users/junhwan2/common/lib/python2.7/site-packages/mercurial/demandimport.py",
line 74, in _load
    mod = _hgextimport(_import, head, globals, locals, None, level)
  File "/Users/junhwan2/common/lib/python2.7/site-packages/mercurial/demandimport.py",
line 43, in _hgextimport
    return importfunc(name, globals, *args)
ImportError: dlopen(/Users/junhwan2/common/lib/python2.7/site-packages/mercurial/osutil.so,
2): Symbol not found: __cg_png_create_info_struct

/Users/junhwan2/common/bin/python2.7: can't open file
'/Users/junhwan2/common/src/yt-hg//distribute_setup.py': [Errno 2] No
such file or directory

As far as I know, yt script needs to make src/yt-hg directory and cp
distribute_setup.py.
Hence, I can not understand what this error for.
Can anyone tell me how it happens and how I can fix it?

FYI, I set DEST_DIR="/Users/junhwan2/common" in the script to install
yt in my home dir.

Thank you in advance,
Junhwan Choi
