After some research the "in place" part is unclear to me. I'll further
research it
though if you could tell me where should I put the cairo and gobject libraries
and what else I might need, that would be of great help.


Brian, thanks for the links. I missed those somehow.
The Alien packages allow the user to seamlessly depend on some
non-perl library.
If Alien::Cairo existed it would either install the cairo C library or skip
installation if there is already one.
The Cairo module then could depend on Alien::Cairo to make sure it
has all the C libraries it needs.

Similarly Alien::wxWidgets provides the wxWidgets C++ library and Wx
is the Perl wrapping of the library (aka wxPerl)
