Please find attached file pkg.sh,  save it in xmlsec ${top_builddir} and 
run. See output for xmlsec1-nss:
....
 -L@pkglibdir@ -lxmlsec1-nss -lxmlsec1 -lxslt -lxml2 -lz -lm
....
No one of scripts configure or config.status contain command to 
substitute @pkglibdir@ and @pkgincludedir@.
Other xmlsec1-*.pc files at moment are not affected, but proprosed patch 
try to fix future problems.

First configure script was run only with --prefix=/usr option and 
without --XXXdir options (especially without --libdir).


just run  "sh -x xmlsec1Conf.sh" without quotes and check the output:
+ XMLSEC_LIBDIR=@XMLSEC_LIBDIR@
....
+ XMLSEC_LIBS=-L/lib -lxmlsec1-openssl ....
....


No one of scripts configure or config.status contain command to 
substitute @XMLSEC_LIBDIR@.
We have two solutions:
- to define this in configure.{ac|in} as in proposed patch;
- to replease @XMLSEC_LIBDIR@ with @libdir@ in xmlsec1Conf.sh.in.


When xmlsec1Conf.sh.in template contain lines:
=======================================
prefix="@prefix@"
exec_prefix="@exec_prefix@"
libdir="@libdir@"
includedir="@includedir@"
=======================================
output is :
....
+ XMLSEC_LIBS=-L/usr/lib -lxmlsec1-openssl ....
....


Now let we comment exec_prefix in template and after "./config.status" 
and "sh -x xmlsec1Conf.sh" output is:
....
+ XMLSEC_LIBS=-L/lib -lxmlsec1-openssl ....
....

differece is -L/lib (incorrect) vs -L/usr/lib (from patch).

Let builddir != srcdir
Command "ln -s $srcdir/Copyright COPYING" will create a link in 
builddir, but  good (default/standard) plase for file COPYING is 
${top_srcdir}.


I'm not sure that configure script should create that link.
$ cd /usr/local/src/.work/.builds/xmlsec1-1.1.0
$ /bin/ls -l COPYING
lrwxrwxrwx    .... COPYING -> 
/usr/local/src/.work/.sources/xmlsec1-1.1.0/Copyright


When is necessary COPYING to be created my suggestion is (xmlsec with 
proposed patch):
$ cd /usr/local/src/.work/.sources/xmlsec1-current
$ /bin/ls -l COPYING
lrwxrwxrwx    .... COPYING -> Copyright


File COPYING exist in ${top_srcdir} (check tar archive) and I think that 
COPYING  should be replaced with a symbolic link (when OS support this) 
in same plase.


Proprosed patch contain replacement of "ln -s" with $LN_S. I don't have 
problems and I don't have OS without symbolic link support. In that case 
I cannot fix a bug :-) I can only suggest a enhancement. May be only in 
hypothetic situation when build dir is located in mounted vfat 
partition. In that case we can see difference between ln -s and $LN_S ;-).

I think that everything works fine too, but suddenly ... :-)
Realy I don't use xmlsecConf.sh and I don't know how to use.
I don't know why to use "pkg-config ... xmlsec1" to get cflags,libs and 
etc. instead of  "xmlsec1-config ..." and my system use OpenSSL not NSS.
My filesystem support symbolic links, i.e. ln -s works fine.

:-)  treat proposed patch as enhancement which fix potential problems ;-)
