# Fedora 14 binary

Dear all,

I just installed sage-4.7-linux-64bit-fedora_release_14_laughlin_-x86_64-Linux.tar.lzma on my computer running Fedora 14:

```
boole[~]$ uname -a
```

Linux boole.math.utk.edu 2.6.35.12-90.fc14.x86_64 #1 SMP Fri Apr 22 16:01:29 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

But I'm getting the following error:

```
ImportError: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.15' not found (required by /work/local/sage-4.7/local/lib/python2.6/site-packages/sage/rings/finite_rings/element_givaro.so)
Error importing ipy_profile_sage - perhaps you should run %upgrade?
WARNING: Loading of ipy_profile_sage failed.
```

I do get a prompt but

```
sage: 2+2
---------------------------------------------------------------------------
NameError Traceback (most recent call last)
/work/local/sage-4.7/local/bin/<ipython console> in <module>()
NameError: name 'Integer' is not defined
```

Can this be fixed or should I just compile it from source.

Thanks,

Luis
