Probably. At least you installed it in /usr/local, not /usr...

For future reference, this is what GNU stow is for: you do

$ ./configure --prefix=/usr/local/stow/packagename

when you build the binaries and then use the stow command to put
appropriate symlinks in to /usr/local/bin, /usr/local/lib etc etc for
the version you want to use. This way you can have several versions
installed in parallel in /usr/local/stow/ghc-6.6.1
/usr/local/stow/ghc-6.8 etc etc, but have one default version
symlinked into your $PATH.

Very useful...

Phil
