Nope, I'm afraid it fails in exactly the same way, whether flex is
installed (it was a dependency of a subsequently-installed package)
or not (finds native lex on Solaris 9).

The config output is a telltale:

[...]
checking for flex... flex
checking for yywrap in -lfl... no
checking for yywrap in -ll... yes
[...]

And the corresponding segment in pcb-current/work/pcb-20040215/config.log:

[...]

Only /usr/pkg/lib/libfl.a was built, no dynamic library, but even
then, the config script can't find it.

It finds /usr/lib/libl.{a|so|so.$ver} OK, but neither -lfl nor -ll are
specified to the linker in:

Either would suffice, but neither are specified.
