I’m getting errors that purelib.rb can’t be found compiling Ruby 1.9  
on MacOS 10.5.2.

ruby trunk r16372

mkdir ruby1.9  
cd ruby1.9/  
svn co [http://svn.ruby-lang.org/repos/ruby/trunk](http://svn.ruby-lang.org/repos/ruby/trunk) src  
cd src  
autoconf  
./configure --prefix=/Users/stephen/dev/ruby1.9  
make

…

gcc -g -O2 -pipe -fno-common -I. -I.ext/include/i686-darwin9.2.2  
-I./include -I. -DRUBY\_EXPORT -D\_XOPEN\_SOURCE -D\_DARWIN\_C\_SOURCE  
-o blockinlining.o -c blockinlining.c  
rm -f ruby  
ruby -Ks ./tool/insns2vm.rb --srcdir=“.” insns.inc  
ruby: no such file to load – purelib.rb (LoadError)  
make: \*\*\* [insns.inc] Error 1

purelib.rb is in ext/ dir:

$ ls ext/purelib.rb  
ext/purelib.rb
