I'm always curious when this comes up: which libraries in particular do you have in mind? If you love Lisp and they're really absent, a short list would at least provide a data point for something that would be desirable and ambitious newcomers could cut their teeth on.
Anyway I don't think the library ecosystem is so dire... Lots of good libraries are distributed through quicklisp. It's pretty straightforward to wrap a C library. (You can even do C++ easily if you switch CL implementations to Clasp...) If you need Java libraries, you can switch CL implementations again and use ABCL. (But of course all your CL code and CL libraries still work.) Lastly, for Python there's https://github.com/pinterface/burgled-batteries (and https://github.com/snmsts/burgled-batteries3 for py3) that even in an incomplete state might suit your particular library needs.
Perhaps this capability isn't very compelling since Python can also access C without trouble (and Java via Jython, .NET via IronPython)? Well I guess all I have left to ask is whether you've considered there might be libraries (or features) in Lisp that would be needed that don't have equivalents in Python? What do you do then? One possible library for admittedly niche applications that came to mind was a hierarchical task planner (https://github.com/shop-planner/shop3) but I forgot someone did indeed make a Python library (https://github.com/oubiwann/pyhop) based on an older version (SHOP1) of the background work, so depending on if you need the v3 features it might suffice.
Thanks for the links! I'll check them out. I like the "higher level" of Python libraries better than C or even Java, because I tend to write what most people would call prototype code. Small user base, small applications, and the really harsh constraint is development time from concept through validation.
No-doubt-unnecessary boilerplate: I understand that people have language wars, and it's possible you may have identified me as belonging to one side or another, but I'll pass. That whole state of affairs is just unfortunate.
