on my local os x machine, i just ran:
sudo gem install curb
and everything worked fine. however, when deploying to our dev ubuntu box, it was not as smooth a process. when running gem install, i got the following error.
Building native extensions. This could take a while...
ERROR: Error installing curb:

after some googling, i determined that i probably needed the libcurl4-openssl-dev package, so i ran the following:
sudo apt-get install libcurl4-openssl-dev
that resulted in:

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
as it turned out, my sources were out of date and when apt-get went looking for the libldap2 packages it needed, they were not there. so i ran:
sudo apt-get update
it updated my sources and i was able to install the libcurl4-openssl-dev package and succesfully install the curb gem. maybe that will help somebody out there.
