host lesstif # emerge -up world

These are the packages that I would merge, in order:

Calculating world dependencies -
!!! all ebuilds that could satisfy "x11-libs/lesstif" have been masked.
!!!    (dependency required by "app-text/xpdf-2.01" [ebuild])
host lesstif # emerge -s lesstif

It seems that it wont honor it as a dep even though it's installed already. 
Here's my info:

Comment 1 J Robert Ray 2003-01-18 23:24:03 UTC
This comes from specifing --update.

'emerge xpdf' would acknowledge that lesstif is installed and would merge okay.

'emerge -u xpdf' wants to try to update lesstif, and at this point the masked
version you have installed becomes "invisible" (because it is masked).  Portage
wants to install an unmasked version but finds none.

This is the same mechanism that tries to downgrade your installed masked
packages to the latest non-masked version during 'emerge -u world'.

My patch from bug 14078 would allow the '-u world' to continue, although it
still would not upgrade xpdf.

I believe Portage is working as designed.  Since your ACCEPT_KEYWORDS does not
allow for masked packages and you've asked it to upgrade, it can't find a way to
give you a non-masked lesstif and errors out.  The erroring out part is not
entirely helpful.

I think the design could be extended to allow an installed package to meet a
dependency when no suitable upgrade can be found, allowing xpdf to be upgraded.

emerge.diff

This patch changes emerge so that when checking dependencies if no installable
(unmasked) candidates exist, but a matching masked version is on disk, the
dependency is considered satisfied.

geep root # emerge -up xpdf

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild    U ] app-text/xpdf-2.01-r1 [2.01]

geep root # emerge -up lesstif

These are the packages that I would merge, in order:

Calculating dependencies
!!! all ebuilds that could satisfy "lesstif" have been masked.

!!! Error calculating dependancies. Please correct.

geep root # emerge -up world

These are the packages that I would merge, in order:

Calculating world dependencies ...done!
[ebuild    U ] app-text/xpdf-2.01-r1 [2.01]

I should mention that in my example I edited xpdf-2.01-r1 to depend on lesstif.
Comment 4 Mark Guertin 2003-01-19 00:41:01 UTC
I was concerned about this because I was sure the previous behaviour was that if 
something that met or beat the dependancy was already install (masked or not) it 
wouldn't complain... but I could be wrong.
