Libtool problems with 1.5.18

[Shreyas Sriniavasan]

Hey,

I have a build of evolution which requires a version of libsoup.  
Initially i had libsoup installed in /opt/gnome/ and later moved it  
to /sw. When i did so i ran a make distclean and re configure before  
i installed to a new prefix.

But while building evolution i see that libtool still searches for  
libsoup in the old prefix. And i get the following error

libtool: link: warning: `/sw/lib/libbonobo-activation.la' seems to be  
moved
libtool: link: warning: `/sw/lib/libbonobo-2.la' seems to be moved
libtool: link: warning: `/sw/lib/libbonobo-activation.la' seems to be  
moved
libtool: link: warning: `/sw/lib/libbonobo-2.la' seems to be moved
libtool: link: warning: `/sw/lib/libbonobo-activation.la' seems to be  
moved
grep: /opt/gnome/lib/libsoup-2.2.la: No such file or directory
sed: /opt/gnome/lib/libsoup-2.2.la: No such file or directory
libtool: link: `/opt/gnome/lib/libsoup-2.2.la' is not a valid libtool  
archive

This breaks my build :(. Clearly libtool should not be looking at the  
old path. I have tried numerous things suggested by online forums but  
havent been able to solve this issue. Is there a patch for the same ?
or any other solution other that is feasible.

p.s: I already tries removing and re installing libtool as suggested  
by a online forum

Thanks,
Shreyas
