I've unmerged linux-headers because it was missing /usr/include/asm/* (that's a topic for another ticket) and /usr/include/linux/* . I unmerged it because I had run out of disk space on /usr while upgrading to 2.4.21-r1 and it had encountered errors. When I try to "emerge linux-headers", it fails because /usr/include/linux/limits.h is missing. If I copy that file from another (x86) Gentoo system, the emerge succeeds. Reproducible: Always Steps to Reproduce: 1. emerge unmerge linux-headers 2. emerge linux-headers 3. Actual Results: It makes it all the way through "make oldconfig", then: >>> make oldconfig complete gcc -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -o scripts/mkdep scripts/mkdep.c In file included from /usr/include/bits/posix1_lim.h:130, from /usr/include/limits.h:144, from /usr/lib/gcc-lib/sparc-unknown-linux-gnu/3.2.3/include/limits.h:132, from /usr/lib/gcc-lib/sparc-unknown-linux-gnu/3.2.3/include/syslimits.h:7, from /usr/lib/gcc-lib/sparc-unknown-linux-gnu/3.2.3/include/limits.h:11, from scripts/mkdep.c:35: /usr/include/bits/local_lim.h:36:26: linux/limits.h: No such file or directory scripts/mkdep.c: In function `add_path': scripts/mkdep.c:221: `PATH_MAX' undeclared (first use in this function) scripts/mkdep.c:221: (Each undeclared identifier is reported only once scripts/mkdep.c:221: for each function it appears in.) scripts/mkdep.c:221: warning: unused variable `resolved_path' make: *** [scripts/mkdep] Error 1 !!!

Is nobody working on this?? I reported it six days ago. In the meantime, my SPARC box is up to 20 packages that need upgrading. I was going to open a separate bug report against linux-headers because, when it *does* install, it still leaves /usr/include/asm empty; consequently most or all of the packages fail to build when I "emerge -u world" or try to build the kernel. But I wanted to wait until this problem (linux-headers won't install without /usr/include/linux/limits.h already being present, but that file doesn't exist without linux-headers) was fixed.
Yup, unmerging packages that are in the profile tends to break things. It's the same with gcc and glibc. Not much we can do about that.
