scrub didn't build on macOS 15

[bengland2]

I was unable to compile scrub on macOS 15 until I edited the src/Makefile to add

-I/opt/homebrew/include

to DEFAULT_INCLUDES

Just FYI, it works fine now. Is ./configure supposed to take care of this? without this change I get:

% make V=1
...
gcc -DHAVE_CONFIG_H -I. -I../config -g -O2 -MT genrand.o -MD -MP -MF $depbase.Tpo -c -o genrand.o genrand.c &&
mv -f $depbase.Tpo $depbase.Po
genrand.c:33:10: fatal error: 'gcrypt.h' file not found
33 | #include <gcrypt.h>
| ^~~~~~~~~~
1 error generated.
make: *** [genrand.o] Error 1

I used the "brew" command to install some of the dependencies for scrub, including the libgcrypt cask, in other words I did:

% brew install libgcrypt

Yes there is a scrub-utility cask, but it doesn't appear to be the same thing as the Linux scrub utility.

Thanks!

Just as a data point, I was able to build scrub (master branch) on Macos Tahoe 26.2 without any special options. It looks like configure didn't find openssl or gcrypt, so scrub defaults to its internal method for generating random data.

I didn't try this but to get gcrypt from homebrew, I would have thought the normal way to do it would be:

CPPFLAGS="-I/opt/homebrew/include" LDFLAGS="-L/opt/homebrew/lib" ./configure ...
