To reproduce this bug: run 'emerge hal' with a Linux kernel 2.6.12 or lower I don't have too much experience in bash scripting (so correct me if I'm wrong) but I think this is a syntax error in linux-info.eclass (in function kernel_is): Basically add '$' in front of 'y'. I have added a proposed patch here: --- linux-info.eclass 2006-04-02 04:39:18.000000000 -0500 +++ linux-info.eclass.corrected 2006-04-02 04:40:33.000000000 -0500 @@ -178,16 +178,16 @@ esac for x in ${@}; do - for((y=0; y<$((3 - ${#x})); y++)); do value="${value}0"; done + for((y=0; $y<$((3 - ${#x})); y++)); do value="${value}0"; done value="${value}${x}" z=$((${z} + 1)) case ${z} in - 1) for((y=0; y<$((3 - ${#KV_MAJOR})); y++)); do test="${test}0"; done; + 1) for((y=0; $y<$((3 - ${#KV_MAJOR})); y++)); do test="${test}0"; done; test="${test}${KV_MAJOR}";; - 2) for((y=0; y<$((3 - ${#KV_MINOR})); y++)); do test="${test}0"; done; + 2) for((y=0; $y<$((3 - ${#KV_MINOR})); y++)); do test="${test}0"; done; test="${test}${KV_MINOR}";; - 3) for((y=0; y<$((3 - ${#KV_PATCH})); y++)); do test="${test}0"; done; + 3) for((y=0; $y<$((3 - ${#KV_PATCH})); y++)); do test="${test}0"; done; test="${test}${KV_PATCH}";; *) die "Error in kernel-2_kernel_is(): Too many parameters.";; esac output from my 'emerge --verbose --debug --info' is as follows: -*- mode: compilation; default-directory: "~/home/workspace/install/emerge/update/10/" -*- Compilation started at Sun Apr 2 04:26:39 emerge --verbose --debug --info Portage 2.0.54 (default-linux/x86/2006.0, gcc-3.3.5-20050130, glibc-2.3.5-r1, 2.6.11-gentoo-r11 i686) ================================================================= System uname: 2.6.11-gentoo-r11 i686 AMD Athlon(tm) XP Processor 2800+ Gentoo Base System version 1.6.14 dev-lang/python: 2.3.5, 2.4.2 sys-apps/sandbox: 1.2.12 sys-devel/autoconf: 2.13, 2.59-r6 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.15.92.0.2-r10 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86" ACCEPT_LICENSE="" ADA_INCLUDE_PATH="/usr/lib/ada/adainclude/gtkada" ADA_OBJECTS_PATH="/usr/lib/ada/adalib/gtkada" ALTERNATE_EDITOR="xemacs -vanilla" ANT_HOME="/usr/share/ant-core" ARCH="x86" ASFLAGS="-Wa,--gen-debug -Wa,-K -Wa,--warn" AUTOCLEAN="yes" BASH_ENV="/etc/spork/is/not/valid/profile.env" CBUILD="i686-pc-linux-gnu" CFLAGS="-march=athlon-xp -pipe -Wall -W -ggdb3 -O0" CHOST="i686-pc-linux-gnu" CLASSPATH="."

Created attachment 83677 [details, diff] patch for the bug basically add '$' before 'y'
Created attachment 83678 [details] 'emerge hal' fails incorrectly without the patch. the script fails due to bash syntax error.
Created attachment 83679 [details] 'emerge hal' fails correctly with the patch added. The script should fail since the hal ebuild requires Linux kernel 2.6.13+ and I have Linux kernel 2.6.11
upon further reading, it seems that the two pieces of script - original and patch - are equivalent in bash. I tend to do all compiles/emerges in GNU emacs 22 and it seems like emacs is not printing the last few lines of the standard error stream in the *compilation* buffer for whatever reason. This seems weird since standard error is an unbufferred stream by default - and it does this _only_ with the original script and not the patched script. So this is most likely a bug in GNU emacs compilation-mode and not in linux-info.eclass.
