The problem comes from signal.h and bits/sigcontext.h. There is an
include asm/signal.h
This dependancy was just recently introduced--I think in FormButton
something.
It is true that most dists do not have symbolic links, but they get
around this by copying those headers to /usr/include/asm so that you
have the kernel headers that libc was compiled with. If you compile a
new libc, as I am going to do today, you need to do something like cp -a
/usr/src/linux/include/asm /usr/include/asm or risk having a new kernel
screw up your libc installation.
And yes, when lyx encounters this problem is says that xforms.h is
missing.
