Another problem with library paths

Hello

I stumbled upon more path errors when trying to install PCRE following 
http://www.linuxfromscratch.org/blfs/view/svn/general/pcre.html. 
Attached pcre.xml gives this when I try to run pcregrep:

dyld: Library not loaded: 
/private/var/folders/ff/m6cylxhd2csdz9fh62g3djtm0000gq/T/0compile-wSab_U/pcre-any-any/lib/libpcre.1.dylib
   Referenced from: 
/Users/iljah/.local/share/0install.net/site-packages/file/Users__iljah__0inst-test__lfs__pcre__pcre.xml/8.37-x86_64/bin/pcregrep
   Reason: image not found
Trace/BPT trap: 5

The reason is (otool -L .../8.37-x86_64/bin/pcregrep):

	/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5)
	/usr/lib/libbz2.1.0.dylib (compatibility version 1.0.0, current version 
1.0.5)
	/private/var/folders/ff/m6cylxhd2csdz9fh62g3djtm0000gq/T/0compile-wSab_U/pcre-any-any/lib/libpcre.1.dylib (compatibility version 4.0.0, current version 4.5.0)
	/private/var/folders/ff/m6cylxhd2csdz9fh62g3djtm0000gq/T/0compile-wSab_U/pcre-any-any/lib/libpcreposix.0.dylib (compatibility version 1.0.0, current version 1.3.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current 
version 1197.1.1)


So 0install/compile didn't adjust the executable for some reason. What 
does work is to emulate a proper destdir install with the attached 
pcre_correct.xml. After running 0compile, copy things from temporary 
directory to final destination with:

cp -r /tmp$HOME/ $HOME

and run

0install run pcre/pcre_correct.xml
Usage: pcregrep [-AaBCcDdeFfHhIilLMNnoqrsuVvwx] [long options] [pattern] 
[files]
Type `pcregrep --help' for more information and the long options.


Could support for this be added to 0install so path adjustments could be 
skipped completely? Two things should suffice:
1) make e.g. PREFIX refer to final destination within interface so 
correct --prefix can be given to configure
2) Do the above copy (something like cp -r $DISTDIR$HOME $HOME) instead 
of regular one (cp -r $DISTDIR $PREFIX ?) when e.g. compile:destdir = 
'true' is set
With these ./configure --prefix=$PREFIX && make && make DESTDIR=$DISTDIR 
install should do the right thing.
Thanks

Ilja
