So does Ubuntu.  That's not a problem.

On Ubuntu, you do

sudo apt-get install guile-1.8-dev

before compiling anything and are set.

GNU/Linux is not Windows: you can usually have several different
versions of libraries installed at the same time.

However, most distributions only allow one _development_ version to be
installed at the same time.  If you are _developing_ more than one
application that compiles with Guile libraries, you need to install the
development libraries and headers back and forth when changing to
_compiling+ for the other application.  But _using_ the compiled
applications with conflicting major library versions in parallel is no
problem.
