<userinput>sed -e 's|in \(.*\$PATH\)|in `echo \1`|' configure...:</userinput>
This fixes a little problem in man's configure. The configure-script
looks for files like cat, gunzip, bzip2, etc. in a for-loop that 
walks through a specified path. The splitting of the path is not done 
correctly and needs that fix.
