I unmerged linux-headers because I'm having problems with it (that's a topic for a different ticket). When I "emerge -u openssh", it merrily goes about trying to configure & build 3.8p1 . Since the configure step requires include files in /usr/include/linux , which are installed by the linux-headers package, the openssh ebuild should be set to require that package. Reproducible: Always Steps to Reproduce: 1. emerge unmerge linux-headers 2. emerge openssh 3.

a _lot_ of packages require linux-headers in this manner ... adding linux-headers to the DEPEND of all of them would be a nightmare
Okay, thanks for explaining that. I wanted to clear that issue up before getting into the next problem I'm having with linux-headers.
note also that the virtual "os-headers" (as supplied by linux-headers) is in system profile. packages resolved and living in the profile for the system need not be in DEPEND, unless there are specific version requirements. There are ofc. some exceptions, like other programs in the profile. And, as virtual/ssh is in the profile (provided default by openssh) this one example -should- have virtual/os-headers listed (or linux-headers) Reopening for that reason.
whatever floats your boat :p
