balsa-1.4.2 /usr/bin/ld: cannot find -lpspell-modules

[julius <juliusjunghans gmx de>]

tried to build balsa-1.4.2, but it cant find the aspell libraries and complains about :

configure: error: *** libpspell(-devel) not found.  Please check 

http://balsa.gnome.org/ for information on the required files.
the last lines in the config.log contain this :

configure:6886: checking for new_pspell_manager in -lpspell
configure:6905: gcc -o conftest -g -O2  -I/usr/local/include/gtk-1.2 -I/usr/loca
l/include/glib-1.2 -I/usr/local/lib/glib/include -I/usr/X11R6/include  conftest.
c -lpspell -lstdc++ -lpspell-modules  1>&5
/usr/bin/ld: cannot find -lpspell-modules
collect2: ld returned 1 exit status
configure: failed program was:
#line 6894 "configure"
#include "confdefs.h"
/* Override any gcc2 internal prototype to avoid an error.  */
/* We use char because int might match the return type of a gcc2
    builtin and then its argument prototype would still apply.  */
char new_pspell_manager();

int main() {
new_pspell_manager()
; return 0; }

whats wrong ?
