Bug 431788 – dev-python/ipython-0.13 does not correctly calculate USE dependencies

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Dustin C. Hatch 2012-08-17 23:12:50 UTC]

The built-with-use dependency logic for dev-python/ipython-0.13 doesn't seem quite right. My first attempt at emerging ipython resulted in this common USE-required message:

The following USE changes are necessary to proceed:
#required by dev-python/ipython-0.13, required by ipython (argument)
>=dev-lang/python-3.2.3-r1 sqlite

Use --autounmask-write to write changes to config files (honoring CONFIG_PROTECT).

After making the appropriate change in /etc/portage/package.use/ipython, I ran emerge -av ipython again, and dependency calculation was successful. Indeed, the emerge proceeded to build and install all of the necessary packages, however, it stopped before emerging ipython with the following error:

 * Please rebuild dev-lang/python:2.7 with the following USE flags enabled: readline sqlite
 * ERROR: dev-python/ipython-0.13 failed (setup phase):
 *   Please rebuild dev-lang/python:2.7 with the following USE flags enabled: readline sqlite

 * Working directory: '/var/tmp/portage/dev-python/ipython-0.13'
 * S: '/var/tmp/portage/dev-python/ipython-0.13/work/ipython-0.13'

Okay, no big deal, I can add readline to my USE flags for Python, but why wasn't this listed at the beginning?

Reproducible: Always

[Comment 1 Jeroen Roovers (RETIRED) 2012-08-18 15:19:13 UTC]

PYTHON_USE_WITH="readline sqlite"

[Comment 2 Mike Gilbert 2012-08-18 22:14:28 UTC]

We would need to migrate to a solution like PYTHON_TARGETS to properly express the dependency.

[Comment 3 Mike Gilbert 2013-05-07 16:11:29 UTC]

Should be fixed in >=dev-python/ipython-0.13.1-r1.
