+Hello !
+Some news :
+Indeed it was more difficult than I thought :
+There were 21 different Makefile.in in 21 directories to modify :
+I wrote a patch that replaces
+-LDFLAGS = @LDFLAGS@
+by
++LDFLAGS = @LDFLAGS@ -lpthread
+in each of them...
+
+Now each Makefile contains :
+LDFLAGS =  -Wl,--as-needed -Wl,--no-undefined -Wl,-z,relro -Wl,-O1
+-Wl,--build-id -Wl,--enable-new-dtags -lpthread
+
+
+And I discover that my first workaround was indeed bad :
+I used
+%build
+%configure2_5x
+%make LDFLAGS="-lpthread"
+
+instead of
+%build
+%configure2_5x
+%make
+
+this allowed to package and I felt happy ;) ... but wrongly happy :(
+
+
+Now that I use a correct LDFLAGS I got new errors about other undefined
+references (thanks to --as-needed option)
+... and I feel sad :(
+
+There came now undefined references to 'dlopen' 'dlerror' 'dlclose'
+
+I had to add -ldl to each Makefile.in
+
+And now it's OK
+
+Thanks to all of you ! I'm now less ignorant than I was ...
+
+But packaging for Mageia will need more skill and more time than for
+Mandriva ... and more patches ! (hope it's worth of it)
+
+I will provide my spec and patch files to anyone (perhaps through
+bugzilla with a package request)
+
+Regards
+Philippe
