Installation error

[Reno]

I've installed one voice, but i can't seem to get another to install. I get this error.

Swift will be installed in the following directories:

Voices in /opt/swift.5.1.0//voices
Shared libraries in /opt/swift.5.1.0//lib
Binaries in /opt/swift.5.1.0//bin
Configuration file in /opt/swift.5.1.0//etc
Header files in /opt/swift.5.1.0//include
Examples in /opt/swift.5.1.0//examples
Sound effects filters in /opt/swift.5.1.0//sfx
Documentation in /opt/swift.5.1.0//doc

Is this acceptable? Enter 'yes' to continue: yes
