Yes to the first. Just installed the second as well.

In the meantime I figured I need this:

sudo apt-get install libcurl4-openssl-dev:i386

However, when I tried to install it, I got:

dpkg: error processing archive 
/var/cache/apt/archives/libcurl4-openssl-dev_7.37.1-1ubuntu3.4_i386.deb 
(--unpack):
  trying to overwrite shared '/usr/bin/curl-config', which is different 
from other instances of package libcurl4-openssl-dev:i386

Does this mean libcurl cannot have both 32- and 64-bit builds installed 
on the same machine?
