Hi Falk

Yes, in my system there are a libdl.a and a libdl.so in usr/lib/.

There are lex and yacc in usr/bin/ though lex is only 21 bytes big.
Perhaps I have a problem with lex?

It reports (in ./configure of kdevelop and of other programs):

checking for yywrap in lfl... yes
or
checking for yywrap in lfl... (cached) yes

And ./configure also reports:

checking for flex... flex
checking lex output file root... lex.yy

Yes perhaps I will try this.
