I am a ruby and rails newbie, so my abilities to debug this are somewhat limited.

I have just added the eclipse plugin which failed, then downloaded the latest aptana studio which also failed. The failure was the same in both cases.

The nature of the failure is that when I create a new rails project, I get an error message about an incompatible library version "C:/Ruby193/lib/ruby/gems/1.9.1/gems/mongrel-1.1.5-x86-mswin32-60/lib/http11.so". The project is actually created, along with directories and files.

Google searches around this error message have only returned a couple of hits, which were not very helpful

I am wondering if this is about 64 bit libraries.

My software stack is:

• Windows 7 home premium 64bit
• Aptana RadRails, build: 2.0.5.1278709071
• Ruby1.9.3 gem 1.8.24

The console shows:

"4320"
