I'm not familiar with "disable-shared", but I suspect it builds static
libraries instead of shared ones. I think you *want* shared libraries.
But if "-pg" is the problem, it's probably GCC. I've got 4.1.2 on my
(Gentoo) systems and I've never seen a problem like this with "-pg". The
only issue I've had at all is that both Ruby and Tcl/Tk have to be built
either with threads or without threads -- you can't mix them.

This works on my box:


# build profiling Ruby
mkdir profiling-ruby-build
cd profiling-ruby-build
CFLAGS='-g -pg' ../ruby/configure --disable-install-doc --enable-pthread
--prefix=/home/test/profiling-ruby
make; make install

If God had meant for carrots to be eaten cooked, He would have given rabbits fire.
