I've encountered a number of strange behaviours with ruby on my new
laptop, which I'd like to setup as a ruby dev envrionment. Dual Core
Dell Latitude D620 running XPSP2 with 2GB RAM, patched, everything else
works fine. I was able for example to install XAMPP (the Windows
packaged Apache/Mysql/PHP distribution) and am able to start MySQL and
Apache from the XAMPP control panel and access PHP applications.
So one would think that I could run Ruby/Rails apps, such as with the
InstantRails package. I am able to download and configure, but when I
attempt to access the rails apps running via WEBrick or Apache, I can
connect, but the application returns no output (e.g. telnet localhost
3000, "GET HTTP/1.0\n\n" returns nothing...it just hangs). Windows
Firewall is disabled, no other firewall stuff installed, Windows
Defender disabled.
So I decided to simplify things and downloaded the stock Ruby install
(both 1.8.2-15 and 1.8.4-17rc2). In both cases when I attempt to run
'gem install rails', the gem program just hangs and doesn't do anything
(I mean for several hours it doesn't do anything). Running 'ruby
-rtracer gem install railes --remote --include-dependencies >
outfile.txt' produces a lot of trace info (101K) that stops here (and
has been sitting here for a few hours):

My theory: something seems to be happening with ruby that's
interfering with socket connections. 'netstat -a' shows:

There was a connection to rubyforge.org but its gone now. The ruby
shell process also does not respond to Control-C events.
I have another laptop running a very similar set of utilities/services
that works fine. But I like THIS machine. :-)
I don't think there's a rails problem or perhaps even a gem problem.
This feels like a low-level problem. Can someone suggest a test program
that would isolate the fault? I've seen a fair number of reports on
various ruby-related lists of this exact problem, but no identification
of the fault or the solution are identified.
I got my RoR book -- I want to get ruby-fied. :-) Someone suggested
"use a *nix VM", which is an idea, but kind of a lame copout.
Any assistance is appreciated.
