Thank you, Sebastian!
That worked.
I am accustomed to using "." in order to run an executable which is not
locatable in PATH.
Having experimented some by writing a trivial non-PATH executable script
and calling it both with and without the preceding ".", I have learned
something new about shell
Thank you, Sebastian!

libdir; however, it is not executable. It is thus unusable as described
in the man page provided via package
Public bug reported:
The binary "gtk-query-immodules-3.0" is absent from package. The package
DOES include the man-page for "gtk-query-immodules-3.0", but not the
actual utility it documents.
I downloaded the source tarball "gtk+3.0_3.22.30-1ubuntu1.debian.tar.xz"
and untar-ed it:
|$ ls ./
