[postgis-users] postgis.sql is failing

[Yurgis Baykshtis]

I followed PostGIS Windows installation steps described here:
http://www.gasai.com/gisapps/WindowsHowTo.html
 
Everything was OK (cygwin, ipc, postgres, build) till the following
statement:
 
psql -U postgres -d myGISdb -f postgis.sql
 
I got the following errors
 
psql:postgis.sql:18: NOTICE:  ProcedureCreate: type histogram2d is not
yet defined
psql:postgis.sql:18: ERROR:  stat failed on file '$libdir/postgis.dll':
No such file or directory
 
And then just whole bunch of these:
 
psql:postgis.sql:23: ERROR:  current transaction is aborted, queries
ignored until end of transaction block
 
Then I tried to execute postgis.sql from the GUI tool (pgAdmin II) and
got the same error:
stat failed on file '$libdir/postgis.dll': No such file or directory
 
I appreciate if anybody could explain what should I do here.
