Team,  
I unzipped ruby 1.9.1 where ruby 1.8.6 was located and since then I am  
having some problems and therefore will appreciate some help.  
Please notice that I still CAN run my ruby scripts, at least the few I  
tried.

C:\>ruby -v  
ruby 1.9.1 (2008-10-28 revision 19983) [i386-mswin32]

C:\>irb  
Generates msg: This application has failed to start because readline.dll  
was  
not found. Re-installing may fix this problem.

But irb actually works after clicking OK on the dialog.

If I try to install any gem (I tried irb & wxruby) I get one or both of  
the  
following two errors, one after the other, in a dialog box:  
Also, if I run gem (for example gem unpack) I get the second error  
(zlib)  
listed below:

This application has failed to start because SSLEAY32.dll was not  
found.  
Re-installing may fix this problem.  
This application has failed to start because zlib.dll was not found.  
Re-installing may fix this problem.

THIS is the first error. I suggest to restore the old directory  
contents and reinstall in another place.

But I am still getting the same errors.  
As you know, Ruby 1.9.1 is a zipped version, which I unzipped on  
ruby-1.9.1.  
I then proceeded to update the path and class variables to reflect  
ruby-1.9.1.  
Any help will be appreciated.

Thank you

Hello “Ruby S.”

You’re getting those errors since you’re missing the binaries required  
to zlib, openssl and readline.

Those binaries exist in One-Click installer because the package  
developers decided to bundle those to ease the users life.

There is no official package for 1.9.1 of One-Click Installer, so you  
will need to manually hunt down (download and extract).

Use as reference the following:
