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

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?
