Possibly a unintentionally masterful gag example of how you'd see someone fail to set something up in php back in the day, or perhaps just a real error. :)
Also well done in the historical use of <table> and <center> tags for layout! In fact, I just realized Hacker News still uses that, I mean, hey no shade.
There were no other dependencies.
Looks like the characteristic error message puts the final realistic touch on what the real thing looks like any more :)
How complete will today's websites render 30 years from now?
