Hello all,
I am stuck and I need your help. I tried to install rails and got the
mkmf error. I installed ruby1.8-dev and I am still getting the same
error.

Rails install error:
--------------------
root@localhost:~# gem install rails
Building native extensions.  This could take a while...
ERROR:  Error installing rails:

load -- mkmf (LoadError)

for inspection.
