[Bashdb-remake] remake and readline relationship?

Hello,

I'm trying to understand the relationship of "remake" building process with
the "readline" library. My machine has the "readline" library already
installed, and also I've installed a most recent version of this library.

If I build the remake without the --with-readline option, then it works OK
in the debugging mode (option -X). If I build the remake with the
--with-readline option, the configure warns me, that the readline library
isn't found, and the built remake can't debug. This warning is below:

configure: WARNING: libreadline is needed for the debugger. I'll build
"make"
configure: WARNING: with trace support, but you won't be able enter the
configure: WARNING: debugger.

The library exists in its normal location:

afy:> ls -l /usr/lib/libreadline*
-rw-r--r-- 1 root root 300808 May  6  2009 /usr/lib/libreadline.a
lrwxrwxrwx 1 root root     16 Dec  9  2009 /usr/lib/libreadline.so ->
libreadline.so.5*
lrwxrwxrwx 1 root root     18 Dec  9  2009 /usr/lib/libreadline.so.4 ->
libreadline.so.4.3*
-rwxr-xr-x 1 root root 192228 Jul 15  2006 /usr/lib/libreadline.so.4.3*
lrwxrwxrwx 1 root root     18 Dec  9  2009 /usr/lib/libreadline.so.5 ->
libreadline.so.5.1*
-rwxr-xr-x 1 root root 208808 May  6  2009 /usr/lib/libreadline.so.5.1*

So - it looks like the --with-readline option works in opposite way.

Also I can't find a way to link the remake with the latest readline library
I've installed myself...

My questions:

(1) What options/envars should I use to configure the remake to point to the
readline library I want?
(2) What's the role of the --with-readline option?

Thanks
AY
