[Ltib] ncurses patching fails

[Mark]

Hello

I've just updated my copy of LTIB via CVS and can no longer get ncurses to 
build because the source cannot be patched:


+ cd ncurses-5.3
+ echo 'Patch #0 (ncurses-5.3-etip-2.patch):'
Patch #0 (ncurses-5.3-etip-2.patch):
+ patch -p1 -s
File aclocal.m4 is read-only; refusing to patch
1 out of 1 hunk ignored -- saving rejects to file aclocal.m4.rej
File configure is read-only; refusing to patch
1 out of 1 hunk ignored -- saving rejects to file configure.rej
error: Bad exit status from /home/mark/ltib/tmp/rpm-tmp.13551 (%prep)


The problem appears to be that the permissions for the relevant source files 
are set to read-only and so the patches cannot be applied. I haven't had (or 
haven't noticed) any problems building ncurses in the past, and I can't see 
that any of the sources have changed recently.

Anybody else had this problem?

Thanks

Mark
