I tried from different computers from different places with different OS,
every time do same thing:

1)Install PLT Scheme, it was not installed on this computer
2)write two lines of code
#lang scheme:
(require (planet schematics/spgsql:2:3/spgsql))
3)and got error message

did not worked with command line tools, I think no need in command line if I was installed fresh PLT Scheme a few times

on my computer with Windows XP I have installed and uninstalled PLT Scheme a few times, and always the same error

also I have a big program, that use "require" (not a two lines of code), and it also do the same error, but there was 2 times when there was no error, and program works
there are some blinking ...

error messages happens different
