Description theroot 2009-06-17 04:19:16 UTC 
Sync'd and remerged world, when I get the error below. Tried to mask the newest updates and it still wont let me continue, has been like this for a few days now, have noticed no bugs here on it yet. Please advise, Thanks!

Reproducible: Always

Steps to Reproduce:
1. emerge --sync
2. emerge -avuDN world (or emerge -avu Compress-Zlib)
Actual Results:  
alpha-centauri ~ # tm -av Compress-Zlib
* Mounting 2250M of memory to /tmp/portage...                                                                                          [ ok ]
* emerging -av Compress-Zlib

These are the packages that would be merged, in order:

Comment 1 Torsten Veller (RETIRED) gentoo-dev 2009-06-17 06:34:47 UTC 
Compress-IO bundles Compress-Zlib, IO-Compress-Zlib, IO-Compress-Bzip2 and IO-Compress-Base, so we can't install the new Compress-IO and any of the old packages.

If any of the old packages

| perl-core/Compress-Zlib
| perl-core/IO-Compress-Zlib
| perl-core/IO-Compress-Bzip2
| perl-core/IO-Compress-Base

is explicitly listed in your world file (grep Compress- /var/lib/portage/world), then there will be a blocker.

Solution:
1) Check if one of them is explicitly listed in your world file
2) In this case it is safe to uninstall the packages
   -or-
   Delete the matching entries from your world file
3) `emerge -uDNav world` should work
Comment 2 theroot 2009-06-17 22:10:03 UTC 
Ah, I didn't know that IO-Compress contains all of those different packages now. unmerge'd those packages and IO-Compress and world update as expected.. Thanks!
