To reproduce the latter issue, i.e. failure to load extensions:

1. Emacs -Q
2. M-x load-library calc RET
3. Evaluate: (setq calc-always-load-extensions t)
4. M-x calc RET
5. Evaluate: (featurep 'calc-aent)

The result will be nil.

Alternately, by using the settings file:

1. mkdir /tmp/emacs-calc
2. HOME=/tmp/emacs-calc emacs
3. M-x calc RET
4. m x
5. m m
6. C-x C-c
7. Repeat steps 2 and 3
8. Evaluate: (featurep 'calc-aent)

The result will be nil.
