Forum OpenACS Q&A: fancy ADP parser is not enabled (OACS4 install msg)

At OpenACS 4 installation (source updated recently from CVS), the following message appears, and won't go away:

At least one misconfiguration was discovered that must be corrected The fancy ADP parser is not enabled. Please add the following to your AOLserver configuration file (usually in /home/aol30/yourservname.ini)

        [ns/server/bquinn/adp] 
        Map=/*.adp 
        DefaultParser=fancy
My openacs4.tcl file has these options set (it was downloaded from file-storage).
To be more specific, at...
set adp_support [ns_config "ns/server/[ns_info server]/adp" DefaultParser]
if { [string compare $adp_support "fancy"] } {
    append errors "

...called from...

/web/openacs4/packages/acs-bootstrap-installer/installer/index.tcl

[ns_info server] returns an empty string; however, my openacs4.tcl contains

set server  "openacs4".
Any ideas?
Starting aolserver with the -s option solved the problem...
/usr/local/aolserver/bin/nsd -s openacs4
