Bug som pred casom reportoval maintainerom.

Prave to tu skusam v RH 5.2 ... a "svete div se", ono to chodi.
Pozeram do SRPM-ka a je tam patch configure.in s datumom 10.9.,
ktory odobera -lieee kniznicu. Cize nieco, co sa floating
point tyka. Ci bolo toto problemom, alebo sa RH 5.2 podarilo
patchnut nieco ine tak, ze to uz s tcltk nekoliduje, netusim,
ale v kazdom pripade to chodi.

Takze skuste tcltk-8.0.3-20.i386.rpm alebo (pokial nejde o RH)
nasledovny patch (nie je velky, tak to snad mailing list znesie).
