Ok.  Though depending on your local set-up, that doesn't really prove
anything.  updatedb skips various files for various reasons (filesystems,
permissions, etc.) Without knowing way more details of your local
set-up, I can't tell whether or nor this actually means anything.
For example, note that your 'locate' command didn't actually locate
blib/lib/libparrot.so, even though your 'nm' command  below shows that
it exists.

Still, that doesn't seem to be the problem.  See below.

Ok.  That's normal.

That's not.  Look at the lower case 't'.  That means Parrot_new is not
a global symbol, but a local one.  I have no idea how that could have
happened.  It was fine in the original src/embed.o file, but somehow got
changed when you make blib/lib/libparrot.so.  I have no idea how.

I do note that you appear to be using an svn checkout, where before you
were using the 0.7.1 released version.  Perhaps there's something broken
in the checkout you have.  Or perhaps there's something not correctly
cleaned up.

The only thing I can think of is to start with a fresh copy and 
log the output of the 'make' command.  Then look at the command used to
build the blib/lib/libparrot.so library so we can try to figure out what
happened to the Parrot_new symbol in going from src/embed.o to
blib/lib/libparrot.so.
