I'm familiar with that thread. ;)  I wanted to play with the CVS 
version and its changed interfaces.

It appears to be a problem with libtool 1.4.2a (used for 
libgcrypt-1.1.11) and libtool 1.5 (sitting on my machine) but not 1.4.3 
(used for 1.1.12).  That is, if I copy libgcrypt-1.1.12/libtool and 
.../scripts/ltmain.sh, into my sandbox, the build proceeds as it 
should.  If I let autogen.sh invoke glibtool (yes, I had to mod autogen 
to pick up GNU libtool under a different name) or copy from 
libgcrypt-1.1.11, I get the clz_tab complaint.

1.4.3 uses the "gcc -r -keep_private_externs -nostdlib" incantation as 
an intermediate step in building the library, while the other versions 
do not (detail below).  That's the only difference I can see, so I 
can't tell what should be done to fix it.

thanks,

1.4.3 does:
/bin/sh ../libtool --mode=link gcc -I/sw/include -g -O2 -Wall   -o 
libgcrypt.la -rpath /usr/local/lib  -version-info 6:1:5  misc.lo 
global.lo sexp.lo stdmem.lo secmem.lo missing-string.lo module.lo 
ath.lo ath-pthread.lo  ../cipher/libcipher.la  ../mpi/libmpi.la 
-L/sw/lib -lgpg-error

-L/sw/lib -lgpg-error -lc -install_name 
/usr/local/lib/libgcrypt.1.dylib -compatibility_version 7 
-current_version 7.1
(cd .libs && rm -f libgcrypt.1.dylib && ln -s libgcrypt.1.5.1.dylib 
libgcrypt.1.dylib)
(cd .libs && rm -f libgcrypt.dylib && ln -s libgcrypt.1.5.1.dylib 
libgcrypt.dylib)

(and succeeds)

while 1.4.2a does:
