I didn't set RPATH.

If I do:

  ./configure CPPFLAGS=-I/home/vlefevre/i386-solaris/include 
LDFLAGS=-L/home/vlefevre/i386-solaris/lib

I get the mismatch. But

  ./configure CPPFLAGS=-I/home/vlefevre/i386-solaris/include 
LDFLAGS='-L/home/vlefevre/i386-solaris/lib -R/home/vlefevre/i386-solaris/lib'

and

  ./configure CPPFLAGS=-I/home/vlefevre/i386-solaris/include 
LDFLAGS=-L/home/vlefevre/i386-solaris/lib 
LD_RUN_PATH=/home/vlefevre/i386-solaris/lib

are OK.

Now, the -R option is non-standard and may fail on some platforms.
