Been getting this error with the latest postgres gem?
% sudo gem install postgres Bulk updating Gem source index for: http://gems.rubyforge.org Building native extensions. This could take a while... ERROR: While executing gem ...

I have, too. I’ve known about the fix for a while, thanks to a post from maintainer Jeff Davis from last month. But I was unable to get it to work. But then I found this gem of a comment (pun not intended) from Gluttonous:
FYI, this does NOT work with sudo since sudo strips the env var out. You must ‘sudo -s’ or ‘sudo su’ and run the command straight up.
D’oh! I’ve been doing this all this time:
ARCHFLAGS='-arch i386' sudo gem install postgres
And getting the same failures. But this works beautifully:
sudo env ARCHFLAGS='-arch i386' gem install postgres
And away we go!
