I have done this but it is not straightforward.
I have had a system install version of ImageMagick (usally an old one
that is from that linux systems repository), and a second one I have
buid with a specific 'prefix'.
The tricky part is that when you want to use a specific version
you build that version yourself using a
configure --prefix=/install/directory
And install it into that directory.
Then when you want to use it you not only call the right executable
(generally set by having the right 'PATH' variable) but that the
executable finds the right library (as per the 'LD_LIBRARY_PATH')
That is the IM you are using finds all its own specific binaries,
libraries, and coders (from the configuration).
If you then want to use a different IM you change the PATH and
LD_LIBRAY_PATH to a different installed version.
DO NOT MIX THEM!
