I’m trying to install mongrel-1.1 (the hot-off-the-press version). I  
have ruby v1.8.6 and it’s running on a Redhat Linux ES server.  
Specifically, I’m facing a problem wherein I get these "No definition  
for " messages during the installation of one of the prerequisites for  
mongrel, viz. fastthread-1.0.1. I’m not sure if these messages are  
just informational or if they indicate some kind of error, but they  
look like “No definition for dummy\_dump” or “No definition for  
rb\_queue\_marshal\_load” or “No definition for rb\_queue\_marshal\_dump”.

Does anybody here have any idea what these messages mean?

Thanks,  
Swaroop
