xfce4-4.3.90.2-installer can't find vte location

[Dale]

Hi there

The installer cannot find my vte.pc file. I've tried to help it along by 
modifying PKG_CONFIG_PATH and by specifying the location manually. The 
installer refuses to enable the Next button and still shows that vte 
0.11.11 or above is not found.

xfce4-4.3.90.2-installer.bin
vte-0.12.0 is installed on my system.
vte.pc is at /usr/lib/pkgconfig/vte.pc

I tried:

# PKG_CONFIG_PATH="/usr/lib/pkgconfig:$PKG_CONFIG_PATH"
# export PKG_CONFIG_PATH

Any pointers would be appreciated.

Thanks
Dale
