no symbol named "*STANDARD-OPTIMIZE-SETTINGS*" in "CL-PPCRE"

[uternet]

Allegro CL reported:

[package cl-unicode]; While EVALUATING an unknown function at top level:
Error: In :IMPORT-FROM list, the symbol "STANDARD-OPTIMIZE-SETTINGS"
not found in package #
[condition type: PACKAGE-ERROR]
Problem detected when processing
(EXCL::DEFPACKAGE-1 (QUOTE :CL-UNICODE) ...)
inside (COMPILER-LET ...)
inside (EVAL-WHEN (COMPILE EVAL ...) ...)

UPDATE:
The cause has been identified! There was a rather old version of cl-ppcre (v1.2.3) in my ~/common-lisp directory, which came from the exercise code in "Practical Common Lisp". After removing this outdated cl-ppcre, everything started working correctly.

I apologize for my oversight.

This symbol should be present, it's imported from cl-ppcre. How are you loading cl-unicode? What is your version of cl-ppcre?

Sorry, I cannot reproduce the issue right now because I have left the machine where the problem occurred. When I tried with another machine, the problem did not occur. Maybe tomorrow I will be able to figure out what happened.
