I think I get your point. On my system the MPFR library is installed in the
standard directory:

$ find /usr/ -iname "mpfr.h"
/usr/include/mpfr.h

But not a single variable from the mkoctfile-help-string printed via
`mkoctfile -p VAR` lists this `/usr/include` directory. Maybe my gcc/g++ is
so kind to include this directory by default and there is something
hardcoded in mkoctfile [1]. So your question is, if the interval package
needs or provides an option to point to (or detect) the MPFR-installation?

I think this is difficult. Usually, users want to install it via `pkg
install -forge interval`. There is no chance to provide a include or library
directory to the pkg command (which would definitely be an overkill). One
can hack around this by changing the some environment variable, for example
running

setenv ("CXX", "g++ -I/usr/local/include")

before the `pkg` command, as mkoctfile seems to look at the environment
variables before execution. But this is everything but user friendly.
