[pacman-dev] weird error when makepkg

[甘露(Gan Lu)]

there are two reports related to my translation (Chinese simplified),
but I can't find any similar items in my po file, so I ask here for
help:
1. when makepkg with -sifr， there are error in finishing:
==> 完成创建：plymouth-git 20100624-1 (2010年 06月 24日 星期四 15:48:46 CST)
/usr/bin/makepkg: line 93: printf: `$': invalid format character
the correspondent line in /usr/bin/makepkg is:  printf
"${GREEN}==>${ALL_OFF}${BOLD} ${mesg}${ALL_OFF}\n" "$@" >&2
sorry for Chinese but this error only occurs in zh_CN environment, C
or en_US.UTF-8 works well.
2. other one is (report by others, I currently don't know what argue
he use 'makepkg'):
/usr/bin/makepkg: line 902: * 1024 : syntax error: operand expected
(error token is "* 1024 ")
the correspondent line in /usr/bin/makepkg is:  size="$((
${size%%[^0-9]*} * 1024 ))"

Anyone?
