I'll immediately give that a try.  However, it seems that it ought NOT
to be an issue, as I didn't symlink stuff until AFTER I built and
installed ruby 1.9.1 AND all the ports (gems).  Only THEN did I create
the symlinks.

Oh, okay.  I get it.  By default, the ruby based ports are expecting
to be installed with 1.8, and even though the build and install WORKS
with 1.9, since I did not set RUBY_VER to 1.9 in make.conf when I
built them. So something somewhere is still thinking "1.8" whether or
not 1.8 even existed (and it did not on my system).


I just uninstalled all gems and ruby related ports, then rebuilt with
RUBY_VER=1.9 in /etc/make.conf.  NOTE: The net/ssh gem was rebuilt and
reinstalled with the ports system.  The mtik gem was directly
installed with 'gem19 install mtik-3.0.1.gem' from the command-line.
I wanted to see if installation method made a different.

ALSO when make was building/installing the gems, I noted these lines
in the output:

Looking at the above install, the 'gem19' install looks like I think
it ought to.


NOW FOR the BIG TEST:

Argh!  The same problem.

So I removed all ruby ports and tried yet again using
RUBY_DEFAULT_VER=1.9 in /etc/make.conf.  Output of the build looked
similar (as above).  And the end result was identical: all attempts to
require the ports failed.



A HA!

This helps:

GEM_HOME=/usr/local/lib/ruby/gems/1.9/ irb19
irb(main):001:0> require 'net/ssh'
=> true

So if I manually set $GEM_HOME, things work.

Any ideas what might be happening, anyone?

Aaron out.


P.S.
Thanks for your help, Stanislav.  I appreciate your suggestions.
