Build fails if directory structure has spaces in directory names

[Discordanian]

My src directory is in a file structure that has a space in one of the directory names and the Makefile fails.

cp -p /Volumes/Zed/Dir Has Space/src/log4sh/src/shell/log4sh /Volumes/Zed/Dir Has Space /src/log4sh/build
cp: /Volumes/Zed/Dir is a directory (not copied)
cp: Has Space/src/log4sh/src/shell/log4sh: No such file or directory
cp: /Volumes/Zed/Dir is a directory (not copied)
make: *** [build] Error 1

Does it work better if you replace lib/shlib_relToAbsPath with the version in https://github.com/kward/shlib/blob/master/functions/shlib_relToAbsPath ?
