LSAPI bug causing site to stall?

I get some errors installing the Ruby LSAPI gem (although it says it installed succesfully) and my Rails site does not respond. The access log reports the hit, and I can see that is being processed in the realtime admin report) but production.log does not report anything. Tried running webrick and it does work just fine so I am guessing there is a problem with the LSAPI.

UPDATE: Looks like even though the gem install says it was succesful it did not create lsapilib.so. What can I do to fix this? Are there any special requirements to build lsapi.so?

LSAPI gem was unable to cleanly compile on your RH EL 2.1 system due to the errors shown in your gem setup stage.

Our linux test systems include Centos 4.4 and Ubuntu Breezy/Dapper.

It might be a compiler compatibility issue with the gcc that came with RHEL 2.1.

Can you give us the ouput of "rpm -qa | grep gcc".

In addition, if we cannot find a RHEL 2.1 iso to test in our vmware setup, we might need to login to your server to debug this error.

It is because your C compiler is picky, the package has been updated to address this. gem version will be available a few hours later after mirror has been synced, the package on our web site has been updated.

RH ES 2.1 is mainly ocmpatible with RH 7.3 I believe. I know when I can find an RPM for 2.1 I try 7.x and it works most of the times.

Here my gcc info:

# rpm -qa | grep gcc
gcc-2.96-129.7.2
gcc-c++-2.96-129.7.2
gcc-g77-2.96-129.7.2

ERROR! Domains cut short!

I was quick to point that the gem now compiled fine but seems to have a problem handling the domain of the request now. Here's the info:

Real Domain: admin.hyperxmedia.net

controller.request.domain : "admin.hyperxm"
controller.request.subdomains : []

I'm not a C programmer but the code that was having problems before looked like it was dealing with the domain. Could you please look at that?

Thanks,

Looks like something wrong with passing the request prarameter.
Can you please try the following code to dump the request parameters in a .rhtml file?

Code: 
<%ENV.keys.sort.each do |key|%>
    <%=key%>=><%=ENV[key]%></br>
<%end%>
And post the result back. I need to get an idea about how bad the request parameters has been messed up.

Thanks.

Just released ruby-lsapi-1.11 to fix another bug in ruby LSAPI code, this bug causes incorrect value for " HTTP_X_FORWARDED_HOST" and " HTTP_X_FORWARDED_SERVER".
Gem version will take a little while to become availabe, you can download the latest version from our web site.
Thanks for your assistance.
