[PHP-INSTALL] make test fails on 5.4.6 with old bugs

Hi,

I've recently built a custom configuration of PHP 5.4.6. ./configure and 
make run without problems, but then make test ends with the following 
failed tests:

Bug #43073 (TrueType bounding box is wrong for angle<>0) 
[ext/gd/tests/bug43073.phpt]
Bug #48801 (Problem with imagettfbbox) [ext/gd/tests/bug48801.phpt]
Test 10: EXSLT Support [ext/xsl/tests/xslt010.phpt]

I can confirm that at least bug #43073 was fixed in the source tarball 
that I'm building. Bug #48801 was reported to be fixed in 2009, so these 
test results really don't make sense to me. Test 10 needs a better 
description for me to understand it more. Does it mean it thinks my 
system doesn't support libexslt (which it does), or that something about 
it is broken?

My system is CentOS 5.2, gcc 4.1.2, glibc 2.5, binutils 2.22. Any 
insights would be greatly appreciated.

Best regards,
Ro Achterberg
