Oops.  Should have used the contents of the date stamp file...

...which means I should have said...
 Line 1473 in m4/libtool.m4 contains the unterminated string.

Hmm, should the name of the file suggest to me that it's part of some
other package, like 'libtool', and I should file a bug report with
it's maintainer?

Guilty as suspected.  My bash and perl is rather old...

I'm not and I won't.  I'll live with my old perl since I don't want to
download and compile perl and bash...  I have a work around and if the
installation fails for somebody else they might have a hack available
when they search the r-bugs/r-devel archive.  Should I encounter the
problem again with a current installation (on a different system),
I'll let you know, otherwise I'll shut up.

True (especially the portability argument) if globbing is handled in
C in Perl nowadays.  I'd challenge the "slower" if Perl had to use the
shell since the shell would sort the file list which readdir won't.

Too embarassed to tell ;-)  Mea culpa, I'll bring up Perl issues in
the future only when I know I have a recent version...
