1. You might want to post this to "gentoo-science"; that's where most |
| 25 |
FORTRAN aficionados, like myself, hang out. |
| 26 |
|
| 27 |
2. How far "very ahead-of-time" are we talking here? I haven't heard |
| 28 |
anything about GCC 4.x on the R mailing lists, which is where I'd expect |
| 29 |
to see the most scrambling about and beta-testing. |
| 30 |
|
| 31 |
3. I think rather than going with your ebuild, I'll build the whole |
| 32 |
thing in a user-space account from virgin upstream downloads. The "whole |
| 33 |
thing" in this case would be GCC 4, a development release of the Atlas |
| 34 |
linear algebra library, and a development release of R and its packages. |
| 35 |
That way it's easier for me to figure out who's messed up without |
| 36 |
burdening Gentoo with upstream bugs. |
