>Description:
Returning to build dependencies leading up to graphics/gimp24:

[...]
===> Installing dependencies for libxslt-1.1.17
=> Required installed package libtool-base>=1.5.18nb5: libtool-base-1.5.22nb3 
found
=> Required installed package perl>=5.8.0: perl-5.8.8nb2 found
=> Required installed package libxml2>=2.6.23nb1: libxml2-2.6.24nb1 found
[...]

OK.  This is still around from the last time I tried to build this
string of dependencies (before pkg/33233 was fixed).  But later, during
the configure phase:

[...]
checking for libxml libraries >= 2.6.25... configure: error: Version 2.6.24 
found. You need at least libxml2 2.6.25 for this version of libxslt
*** Error code 1

Stop.
bmake: stopped in /usr/pkgsrc/textproc/libxslt
[...]


pkgsrc's dependency check disagrees with that of the distfile's
configure script.
>How-To-Repeat:
On MacOS X, with libxml2-2.24nb1 or earlier installed, and pkgsrc
updated to pkgsrc-2006Q2 (or later?), attempt to build textproc/libxslt.
>Fix:
A workaround would be to explicitly deinstall the old libxml2 and
restart the build process.

The following patch causes pkgsrc's version dependency to reflect that
expressed by the distribution configure script:

As patched, textproc/libxslt's dependency check causes a build of
libxml2-2.26.  libxslt then proceeds to configure and build.
