<br>
</span>The purpose of the conf-gnomecanvas package is to check that you have<br>
the appropriate system package for the libgnomecanvas library<br>
installed. The description (which you can see with 'opam show<br>
conf-gnomecanvas') says:<br>
<br>
This package can only install if libgnomecanvs2.0-dev is installed<br>
on the system.<br>
<br>
OPAM can also list the system package dependencies for you:<br>
<br>
opam list conf-gnomecanvas --external<br>
<br>
So the following should help:<br>
<br>
sudo apt-get install libgnomecanvas2.0-dev<br>
<br>
You might also be interested to know that the Universe Library now has<br>
OPAM support, so the following will install the OPAM dependencies and<br>
build and install the package:<br>
<br>
opam pin add universe <a href="https://github.com/kenichi-asai/Universe" target="_blank">https://github.com/kenichi-asai/Universe</a><br>
<br>
Finally:it's best not to run OPAM using 'sudo'. It's designed to run<br>
with normal user permissions and install files under your home<br>
directory.<br>
