Hi,  
I am trying to update passenger for 10.6, and I am getting an error  
relating to fastthread… passenger thinks fastthread is missing.  
Here’ the apache error log output:

fastthread.bundle:

I installed fastthread threw ruby gems and didn’t get any errors  
aside  
from some ri and rdoc errors (missing variables).  
I then installed it from the tar package available on rubyforge. But  
I still get the following error when I tried to reinstall the  
passenger apache module:

- fastthread… not found  
Does anyone know where passenger is looking for the fastthread  
bundle?  
I made symbolic links to it in /usr/bin and /usr/sbin, just in case,  
but that didn’t help. Currently my install of fastthread is at /usr/  
local/lib/ruby/site\_ruby/1.8/i686-darwin8.10.1/fastthread.bundle  
Thanks in advance for any ideas.  
Sean

Hi, did you rebuild all native gems after installing Snow Leopard and  
their associated development tools? If not, then you should read the  
following:

BTW, I have been using Snow Leopard and Passenger without any  
issues.

Good luck,

Thanks for the idea. I had already updated everything. The problem  
turned out to be that for some reason, my installation of ruby was  
still at 1.8.6 instead of 1.8.7 that is supposed to be installed with  
snow leopard. in my case it wasn’t, not sure why, but the passenger  
install script only requires the fastthread library in ruby versions  
lower than 1.8.7. So I installed ruby 1.8.7 from source, and now  
everything seems to be working.

thanks,
