Yes:

If I leave it out (which was my first try anyway) I get this error message:

/gnu/store/k7029k5va68lkapbzcycdzj7m5bjb4b8-bash-4.4.12/bin/bash ../libtool

../libtool: line 6000: cd: yes: No such file or directory

It seams the semantics for --with-libtiff is different than for the other
libraries.

Good catch. It should be API-compatible, available on all plattforms and
Arch and Ubuntu (checked these) use is as dependency for libgeotiff.

I will give it a try and hopefully will also pack a minimal version of
GDAL to really make use of the library.

Thanks,
