@elcore - as mentioned in my OP, I thought I had removed all references and started 'clean' as such - or as best I can tell.
It did not make any difference. I suspect it is a 'quicklisp' [compatibility with CLISP] error (not sure).
From a running clisp built from 'current' (and following download of quicklisp.lisp), evaluating '(load "quicklisp.lisp")' and then '(quicklisp-quickstart:install)', eventually delivers the following:
DEFPACKAGE QL-CLISP: There is no symbol EXT:
ELETE-DIR .
If you continue (by typing 'continue'): This symbol will be created.
The following restarts are also available:
RETRY :R1 Retry compiling #<CL-SOURCE-FILE "quicklisp" "impl">.
ACCEPT :R2 Continue, treating compiling #<CL-SOURCE-FILE "quicklisp" "impl"> as having been successful.
SKIP :R3 skip (LET # #)
RETRY :R4 retry (LET # #)
STOP :R5 stop loading file /home/bch-slack142/quicklisp/setup.lisp
ABORT :R6 Abort main loop
Break 1 QL-IMPL[3]> continue
That's why I was wanting to know if anyone building/maintaining/using clisp from current and using quicklisp was doing so without any issues.
I'm just a beginner with lisp/clisp, so I'm going to be a bit unhelpful to start with. I will refer the error to the quicklisp discussion group for ideas as it looks like a quicklisp compatibility [to CLISP] related error, in my ignorance.
Of course, if I revert pack to the packaged clisp version (rather than using 'current'), all this seems to go away :-)
Thank you.
