pgaccess error

Why I get this error when I tried to run pgaccess

tcl error executing pg_exec
select relname from pg_class
where relname = 'pga_queris

invalid option pg_result result
?option?where?option is
- status
- conn
- assign
arrayVarName
-assignbyidx

arrayVarName
- num Tuples
- attributtes
- lAttibuttes
- num Attrs
- get Tupple
Tupple Number
- Tuple Array
tuple Number array VarName
- clear

when I click OK it close back the program.

I used redhat 5.1
I download pgaccess 0.91
I also donwload the redhat-5.1-pg-6.3.2-libpqtcl.so and libpq.so but
I do not know to use it.
What should I do with this to lib.
if must to compile how I want to compile(I never compile before
this).

Thanks.
