[sbopkg-users] strange error depending on run directory

[mc collilieux]

Hello, I am a new member of this list, with slackware 12.1
I have a little problem with sbopkg, in line 99
KEEPLOG=$(echo "$KEEPLOG" | tr [[:lower:]] [[:upper:]])

when I run it (as root but in my user home) i have this error message:

tr: construit [[:upper:]] et/ou [[:lower:]] mal aligné
(tr: built [[:upper:]] and/or [[:lower:]] misaligned ?)

ERROR
sbopkg: Can't find a value for variable(s):
KEEPLOG

when I run it outside \home\myuser, it's OK, strange ? What can be this 
problem, I think perhaps false rights ?
