Just manually force mercurial to install via 

   sage -f mercurial-1.1.2.p0

then type "make" (or "sage -upgrade") after that finishes to continue the upgrade.

I think this caused by a mistake in the spkg/standard/deps file.  These lines are wrong:

$(INST)/$(EXTCODE): $(BASE)
        $(SAGE_SPKG) $(EXTCODE) 2>&1

since clealry installing the EXTCODE package depends on mercurial.  It should be:

$(INST)/$(EXTCODE): $(BASE)  $(INST)/$(MERCURIAL)
        $(SAGE_SPKG) $(EXTCODE) 2>&1

[mvngu]

The file SAGE_ROOT/spkg/standard/deps has been changed so that now the lines for extcode are:

# Mercurial must be built before building extcode. See trac ticket #6508.
$(INST)/$(EXTCODE): $(BASE) $(INST)/$(MERCURIAL)
        $(SAGE_SPKG) $(EXTCODE) 2>&1

I'm building Sage 4.0 from source on sage.math so that I can test upgrading from that version to the latest rc release of Sage 4.1.1. This should take a while to test.

[mvngu]

The above changes seem to be working fine for me. I'm releasing these changes with Sage 4.1.1.rc1 so others can test upgrading from Sage 4.0 to 4.1.1.rc1. If all goes well, this ticket would be closed as being merged in Sage 4.1.1.rc1.

[mvngu]

This has been fixed in Sage 4.1.1.rc2. So I'm closing this ticket as fixed.
