Description of Problem:

When trying to rebuild lftp-2.3.11-2.src.rpm I need to have lftp already
installed. Else there are appearing messages like

-----------
mkdir /var/tmp/lftp-2.3.11-root/usr/lib/lftp/2.3.11
/bin/sh ../libtool --silent  --mode=install /usr/bin/install -c

------------------

while the %build-stage. The corresponding modules (proto-ftp.so &
proto-http) are missing in the package also. Therefore lftp won't be able
to handle ftp or http.

The other modules (proto-file,libnetwork,cmd-sleep,cmd-mirror) are ok.


How Reproducible:

evrytime


Steps to Reproduce:
1. uninstall lftp
2. rpm --rebuild lftp-2.3.11-2.src.rpm
3. rpm -qlp lftp-2.3.11-2.i386.rpm


Actual Results:

no proto-http.so or proto-ftp.so file


Expected Results:

/usr/lib/lftp/2.3.11/proto-ftp.la
/usr/lib/lftp/2.3.11/proto-ftp.so
/usr/lib/lftp/2.3.11/proto-http.la
/usr/lib/lftp/2.3.11/proto-http.so
