You seem to be suggesting what he *should have done* |
| 30 |
The point is, he has already installed multiple (at least 3.0.1 and 2.6.2) |
| 31 |
vanilla ("fresh" from http://www.python.org/download/releases/) |
| 32 |
python versions manually (with |
| 33 |
./configure -with-fpectl -infodir=/usr/share/info/ -mandir=/usr/share/man |
| 34 |
make |
| 35 |
make install prefix=/usr |
| 36 |
) |
| 37 |
and then he tried emerge -va python |
| 38 |
|
| 39 |
He followed instructions from this damn blog |
| 40 |

| 41 |

I fear that his system is now a mess, with remains of multiple python versions. |
| 43 |
I suggested a idea for how to clean it up (read the quoted text above, |
| 44 |
starting with "One idea:") |
| 45 |
|
| 46 |
Anyway, some conclusions: |
| 47 |
- The blog solution seems to be a quite bad one, for multiple reasons. |
| 48 |
- A better and easier solution would be to install a binary package from |
| 49 |
tinderbox. I think he wouldn't even have to extract the tarball manually |
| 50 |
with tar; he can use qmerge from portage-utils (written in C AFAIK); I'm |
| 51 |
not sure, haven't used qmerge so far |
