I just tried to install the latest luarocks from the Github repo
master (SHA1: 143cc28429)
on the Mac OSX 10.6.8 (Snow Leopard). 'make build' resulted in error
sed: -: No such file or directory
which I was able to trace to a complex and fragile definition of
SAFEPWD variable in the main Makefile.
SAFEPWD=`echo "$$PWD" | sed -e 's/\([][]\)\1/]]..'\''\1\1'\''..[[/g' -`
Removing this variable and replacing it with a regular $$PWD solved the problem.
I am curious, what's the point of sanitizing PWD value?
Is it an attempt to prevent malicious use of path names:-)
