I would try to figure which systems use pkgconfig and if many/all
linux distros do that (which I guess is mostly all by now, as many
other "basic in Linux" software require, not just allow, pkg-config
for building), use the following lines (for static linked) and thus
make it work in many/all:

NAN_OPENEXR=$(shell pkg-config --variable=prefix OpenEXR )
NAN_OPENEXR_INC=$(shell pkg-config --cflags OpenEXR )
NAN_OPENEXR_LIBS=$(addprefix ${NAN_OPENEXR}/lib/lib,$(addsuffix .a,$(shell pkg-config --libs OpenEXR | sed -s "s/-l//g" )))

What about commiting something like this and see how many people
complain? In worst case it would mean people have to install pkgconfig
if they had not built anything ever, but no big problem about finding
it as it should be in many/all distros already.

Or just go with /usr as with other system level libs, otherwise we
keep with the problematic setting as we have done for months, at least
since February (scons uses /usr, and both make and scons use
sdl-config for sdl things, BTW). Sorry to be a bit blunt, just do
something and see if that solves it, there is cvs if needed to go
back.

About looking, quick searchs show that Debian (and derived should
too), Fedora Core / Red Hat, Suse, Mandriva and Slackware go with /usr
and have OpenEXR.pc (correct me if wrong, they were really quick). For
Gentoo I no idea if /usr as I do not know how to interpret their build
config nor have a system handy, but I see strings like "mv
${D}/usr/share/doc/${P}/examples ${D}/usr/share/doc/${PF}/examples"
and they depend on pkgconfig.
