No it will probably not. You must understand though that adding something to |
| 11 |
DEPEND only tells portage that that package should be available, but it does |
| 12 |
not change the build process or it's native checks. As such the package |
| 13 |
itself searches for headers and libraries in the root directory. The ROOT |
| 14 |
feature makes it such that the actual moving of files will not happen in the |
| 15 |
base distribution but somewhere else. This is equivalent to running with the |
| 16 |
-B (build package, don't install) function and later installing the binary |
| 17 |
packages from a chroot. |

That is not possible, the only way to do it is with a chroot jail such that |
| 30 |
you create a similar environment. |

RDEPENDS do nothing for the build process. They only need to be there for the |
| 36 |
package to run. |
