Gem + libxml

Hi

Wat is wrong here ?? Do I need ruby source?

linux:~ # ruby -v
ruby 1.8.2 (2004-12-25) [i586-linux]
linux:~ # gem -v

Hmm, I think that the Ruby headers should always be installed, in your
case it looks like they should be at:

/usr/lib/ruby/1.8/i586-linux/

Could you verify the presence (or absence) of a bunch of .h files at
that location? If they’re not there, then you should probably grab a new
Ruby install (is this one a package from your distro?).

Ruby comes with distro ( SUSE 10)

Okay, it seems you’re missing the headers. Couple of things you might
try:

+ Does Suse have a ruby-devel package ? If so, get that.

+ Beg/borrow/steal the appropriate headers, and copy them to
  that directory (maybe not a good idea).

+ Alternatively, grab a copy of the source and build it
  yourself. You could upgrade to 1.8.4 at the same time ;)

There was a ruby-devel pakage, now it works!! Thanks for your help
