My emerge of dev-libs/nss-3.12.5-r1 would result in linker failures about missing symbols like PL_strlen. I eventually realized that this was due to a -L flag with nothing after it, making the subsequent -lplc4 flag be misinterpreted as a library path. I tracked this to NSPR_LIB_DIR=`pkg-config --libs-only-L nspr | sed 's/-L//'` in the nss ebuild. That command yields no output. nspr.pc has this line: Libs: -R${libdir} -L${libdir} -lplds4 -lplc4 -lnspr4 -lpthread I suspect that '-R' should be '-Wl,-R'. Somehow this means that even when only looking for -L, pkg-config isn't willing to print anything... This nspr.pc comes from dev-libs/nspr/files/nspr-4.8-pkgconfig-gentoo-1.patch I've since rolled back to stable nspr and nss (I didn't intend to install these versions; turns out my old unmasks for installing firefox 3.5 when it was new were just too wide), so I can't really reproduce this any more without having to recompile vast swaths of my system. However, you should be able to reproduce by emerging nsnpr-4.8.3 and then nss-3.12.5-r1.
Your understanding is wrong, without proper emerge --info and being willing to work on the problem I see no way to address this issue. Reopen when you are willing to debug why your missing an export via the ebuild.
I am willing to help debug. Turns out I didn't have to rebuild that many things due to nspr/nss. Sorry if I sounded unwilling before; I just wanted to move on and get a working system before coming back to this. I'll provide emerge --info when I get back home. Sorry I didn't include it before; highlights off the top of my head include ARCH=amd64, CFLAGS="-O2 -march=athlon64", MAKEOPTS="-j2" (varying this had no effect) If you read this in the meantime, can you clarify where you think my understanding is wrong?
Both these exports are run first. export PKG_CONFIG_ALLOW_SYSTEM_LIBS=1 export PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1 This is how we are able to get a proper libpath for the libs we need. export NSPR_INCLUDE_DIR=`pkg-config --cflags-only-I nspr | sed 's/-I//'` export NSPR_LIB_DIR=`pkg-config --libs-only-L nspr | sed 's/-L//'` If the exports do not happen, we will end up with a null return on NSPR_INCLUDES_DIR and NSPR_LIB_DIR. This is all well tested on amd64. Soon as you can please provide your emerge --info and your enviroment file so we can trace where your failure is actually occuring.

I made a mistake in my original report: It was nss-3.12.5 (stable), not -r1 (unstable) that failed to emerge, and it was with nspr-4.8.3-r2 (unstable), not 4.8.3 (stable). These versions of nss and nspr ebuilds are probably just incompatible, and given their different states of stability should not be expected to work together. emerging only the unstable (nspr-4.8.3-r2 and nss-3.12.5-r1) versions works fine. So, this is just user error, perhaps with a little missing dependency checks mixed in. I'm closing as invalid. Sorry for your time.

Sorry for your time. > Glad you figured out where you problem was, I double checked the ebuild, and based off your findings I am lead to believe you have an older version of the tree before I fixed the dep. Sorry this caused used problem. Please never hesitate to file a bug if you believe you have a valid bug or just need help.
