When running make install, the libraries are re-linked. That might be
what you see.
Another possibility is that you use different options for install (in
which case everything compiled with different options will be
automatically re-compiled).

If you change one of the main Makefile*, everything will be re-compiled
(everything depends on the Makefile, if you change some option in it,
everything has to be re-compiled).

It works perfectly for me. Maybe you have a strange modules.lst? (try a
make proper, although for me it works without it)
BTW: the easiest way to include your module temporarily (only for one
build) is: make include_modules=pua modules-all. To include it
permanently: make modules-cfg include_modules=pua.
To only compile only your module: make -C modules_k/pua .

You can see the list of the modules that will be compiled, the list of
extra included modules and the list of excluded modules, by running:

make print-modules

E.g.: in your case, try:
make print-modules |grep --color pua
make print-modules exclude_modules=""|grep --color pua
make print-modules include_modules=pua|grep --color pua


All this commands are documented in INSTALL (not in the most friendly or
 structured way though):

  - change & save the  modules list without rebuilding the whole config
    (so that already compiled modules won't be re-compiled by 
    make all/make modules):
    make modules-cfg include_modules="mysql postgress"

...
  NOTE!!! As this mechanism is very powerful, you may be uncertain which
  modules that will be included. Just replace all (or modules) with
  print-modules and you will see which modules will be included and excluded,
  ex:
    make print-modules

...
  * make cfg or make config - force config and module list regeneration
  Example: 
    make cfg include_modules=mysql mode=debug
...

  * make cfg-defs  (force config regeneration, but don't touch the module list)

    make modules-cfg
  or
    make modules-list
  saves the module list, without regenerating the build config
  Example:
    make modules-list include_modules="tls" skip_modules="print"
