[gentoo-amd64] Linker search path issue..

[Eoin Hennessy]

I have gtk+-2.8.0 installed under /usr/local and have included
/usr/local/lib64 in /etc/ld.so.conf (and have run ldconfig). I have
also listed this path in LD_LIBRARY_PATH. I have successfully built
other autotool based gtk+ apps, but when I go to emerge/build
libgnomecanvas-2.10.2 linking fails with the following output:

I am not familiar enough with libtool to determine why it is expecting
libgtk-x11-2.0.la in /usr/lib64 when it is present in
/usr/local/lib64, which seems to be in the linkers search path. 
Moving gtk+ to /usr is an option but I'm curious as to the cause of
this issue.

This is an amd64 installation with gentoo base system version 1.4.16.
I am using;
   libtool 1.5.10-r4,
   autoconf 2.59-r6 and
   automake 1.9.4

Thanks in advance for any help, or pointers to where this question may
be more appropriate.
