Getting cannot resolve host error when trying to install RVM on osx lion

I have everything preinstalled .. I'm on osx lion 10.7.2

Xcode:

$ xcodebuild -version
Xcode 4.2.1

git:

$ git --version
git version 1.7.5.4

when I run $ bash <<(curl -s https://rvm.beginrescueend.com/install/rvm )

I get the following error:

curl: (6) Failed to resolve host: HD; nodename or servname, or not known Failed to download 'https://github.com/wayneeseguin/rvm/tarball/master'.

any ideas why? If I run as sudo, it passes, but then I get more errors ... I need to install it as a single user. path to my home directory:

'/volumes/Macintosh HD/users/mikedevita'
