That is unlikely. PyD is just a D package, it doesn't have the 
ability to mess up with your project files to pack proper 
shippable app.

On linux it also adds complexity due the way how dynamic 
libraries are handled (i.e. need to set this fancy RPATH, 
LD_LIBRARY_PATH, whatever else necessary), so I would first make 
isolated python copy using venv(and install required packages) 
and then copy it to your final redistributable dir, might also 
require messing a bit with linker flags (to tell where to look 
for shared libs), but anyway it all depends on what prebuilt 
python depends, for example it will likely fail if run on older 
distro or just distro with older libc, or if any of its other 
dependencies being older or missing.


As for py_import issue you can also try do import within py_stmt 
and see if it works(assuming python has all relevant paths set 
up).
