>Description:
Build fails with:

[...]
checking for XTHREADS in Xlib... yes
checking for xrender >= 0.8.2... yes
checking XRENDER_CFLAGS... -DXTHREADS -I/pkg/include -I/usr/openwin/include 
checking XRENDER_LIBS... -L/pkg/lib -L/usr/openwin/lib -Wl,-R/pkg/lib -lXrender -Wl,-R/usr/openwin/lib -R/usr/openwin/lib -lX11 
checking for xfixes... Package xfixes was not found in the pkg-config search path. Perhaps you should add the directory containing `xfixes.pc' to the PKG_CONFIG_PATH environment variable No package 'xfixes' found
configure: error: Library requirements (xfixes) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
*** Error code 1

Stop.

Setting PKG_CONFIG_PATH to the directory containing xfixes.pc does not help.
