[gentoo] 升级了system & world

其间遇到一些问题,当unmerge libgnome等包的时候,出现Colorset-Author command not found之类的,列举如下(一般会报等号左边的命令找不到)

最后提到:
i had the same problem..

代码:

/var/tmp/portage/app-text/xpdf-3.02-r1/temp/environment: line 6: Aumix-VolumeAmo
unt-Button=10: command not found
/var/tmp/portage/app-text/xpdf-3.02-r1/temp/environment: line 7: Aumix-VolumeAmo
unt-Wheel=2: command not found
/var/tmp/portage/app-text/xpdf-3.02-r1/temp/environment: line 17: Colorset-Autho
r=fRiQ: command not found
/var/tmp/portage/app-text/xpdf-3.02-r1/temp/environment: line 18: Colorset-Name=
DarkDesktop: command not found
... etc

finally i solved it in that way:

引用:

in file /usr/lib/portage/bin/ebuild.sh

filter_readonly_variables() {
[...]
my_var_grep="^(|(declare.*))[[:alnum:]]+(-[[:alnum:]]+)+(=.*)"
var_grep=${var_grep:1} # strip the first |
var_grep="(^|^declare[[:space:]]+-[^[:space:]]+[[:space:]]+|^export[[:space:]]+)(${var_grep})=.*|${my_var_grep}"
[...]
}

i know it isn't good, and any reemegre portage will destroy it, but... it's all i can do now
