garnome-2.9.2.1 : compilation error with evolution

[Eric Le Bourvellec <eric lebourvellec free fr>]

First I had :
camel-smime-context.c:36:17: cms.h: No such file or directory
camel-smime-context.c:37:18: cert.h: No such file or directory
camel-smime-context.c:38:20: certdb.h: No such file or directory
camel-smime-context.c:39:20: pkcs11.h: No such file or directory
camel-smime-context.c:40:19: smime.h: No such file or directory
camel-smime-context.c:41:21: pkcs11t.h: No such file or directory
camel-smime-context.c:42:22: pk11func.h: No such file or directory

Then I installed libnss3-devel-1.7.2-11mdk.i586 + 
libnspr4-devel-1.7.2-11mdk.i586 which needed to uninstall 
mozilla-firefox-devel-1.0-0.1.101mdk.

But then I got :
e-msgport.c:39:18: nspr.h: No such file or directory
and nspr.h comes with package mozilla-firefox-devel-1.0-0.1.101mdk which 
needs to uninstall libnss3-devel and libnspr4-devel.

It's going round in circles !
So is anybody knows how to resolv this ...

thanks
