can't start pgaccess

Hello,
I installed pgaccess-0.98.7, but I get the following error message when
I try to start it:
Error in startup script: couldn't load file "libpgtcl.so": libpgtcl.so:
cannot open shared object file: No such file or directory   while executing
"load libpgtcl[info sharedlibextension]"   (procedure "main" line 3)   invoked from within
"main $argc $argv"   (file "main.tcl" line 249)

Long time ago I was able to solve this problem by putting a symbolic
link in pgaccess/lib/ directory to
postgresql/src/interfaces/libpgtcl/libpgtcl.so. For some reason it does
not work now.
Please help
Thanks

Oleg
