Yes, but that is not compliant with _our_ packaging standards. You have
to have a -shlibs splitoff if this is a library that can be built
against by other packages, or you can mark the library as private if the
library is only used here and there aren't any header files to allow
other packages to build against it.
The fact that it runs is immaterial, since unversioned dylibs are
usually symbolic links that are only needed at build time.
How about posting the results of "dpkg -L libdmtx"? That way we can see
what's in the package and how you might want to think about carving it
up into splitoffs, if needed.
And why are you marking it as BuildDependsOnly: true? That's normally
reserved for header packages.

$ fink list -t libpng
Information about 10490 packages read in 1 seconds.
libpng-shlibs 1.0.12-7 PNG image format handling library (old
version)
libpng14 1.4.2-1 PNG image format handling library
i libpng14-shlibs 1.4.2-1 Shared libraries for libpng14 package
i libpng3 1:1.2.43-3 PNG image format handling library
i libpng3-shlibs 1:1.2.43-3 Shared libraries for libpng3 package
i system-pkgconfig-libpng 1.2.43-1 [virtual pkgconfig package
representing libpng]
i system-pkgconfig-libpng12 1.2.43-1 [virtual pkgconfig
package
representing libpng12]
The only virtual packages are the pkgconfig-related ones, which are not
relevant here as far as I know. Give it an explicit dependency on
libpng3 or libpng14.
i'm not sure how to best deal with the Depends: field as far as
> how specific to make the version numbers, etc.. any suggestions here?
Start by actually listing the dependencies and the matching BuildDepends.
