I installed cl-yacc from quick lisp:
(ql:quickload "yacc")
I checked it is available.
[12]> (ql:system-apropos "yacc")
#<SYSTEM lispbuilder-yacc / lispbuilder-20130312-svn / quicklisp 2013-08-13>
#<SYSTEM yacc / cl-yacc-20101006-darcs / quicklisp 2013-08-13>
I tried to use the package, but I got errors.
[18]> (use-package '#:yacc)
*** - USE-PACKAGE: There is no package with name "YACC"
The following restarts are available:
USE-VALUE :R1 Input a value to be used instead.
ABORT :R2 Abort main loop
[20]> (use-package 'yacc)
*** - USE-PACKAGE: There is no package with name "YACC"
The following restarts are available:
USE-VALUE :R1 Input a value to be used instead.
ABORT :R2 Abort main loop
What might be wrong? How to use the package? I use clisp under Mac OS X 10.7.5
