I should also say I am interested in getting the Xubuntu installation
to work more than I am in just getting my own account to work.
Also, I have just installed Saucy on a laptop, fresh 64-bit install.
I tried some things, I forget which, and one of them pointed me at the
package ruby1.9.1-full and on installing that, everything worked.
So I went back to this machine running Raring, and find that while I
have ruby1.9.1 installed (and it's an Ubuntu package) I do not have
ruby1.9.1-full installed, and it is NOT an Ubuntu package. On
installing ruby1.9.1-full, I find all these problems have gone away.
It seems to me that Ubuntu should either drop ruby1.9.1 or adopt the
full version as well. What they have now is an embarrassment.
