Build problems (RTLD_DEFAULT)

[Adam K Kirchhoff]

Hello all,

I've managed to get Xorg built, using jhbuild, on two boxes now, and am
moving on to a third.  All three boxes are ubunty edgy.  On this
particular box, though, I've run into a new problem:

        gcc -DHAVE_CONFIG_H -I. -I. -I../../../include
-I../../../include -I../../../include -I../../../include
-I../../../include -I../../../include -I../../../include
-I../../../include -I../../../hw/xfree86 -I../../../hw/xfree86/include

-DXF86PM -g -O2 -c dlloader.c
dlloader.c: In function 'DLFindSymbol':
dlloader.c:116: error: 'RTLD_DEFAULT' undeclared (first use in this
function)
dlloader.c:116: error: (Each undeclared identifier is reported only once
dlloader.c:116: error: for each function it appears in.)
make[4]: *** [dlloader.o] Error 1

I've checked, and dlloader.c includes dlfcn.h, which appears to define
RTLD_DEFAULT.

Again, I didn't encounter this error on either of my other two boxes,
but I'm not sure if that's because I built Xorg last week on those and
something has changed since then, or if there's just something else
strange going on.  Any ideas?  Thanks!
