Hi Fabrice,

I started playing with qserv eups-based install process and learning 
eups along the way. I just went through the first step by checking out
u/fjammes/eupspkg branch and running install.sh script. I decided 
to look around for what eups does and how it arranges things. Looking 
at table files in instalation area I observed one interesting thing 
that I don't quite understand. Basically some table files have 'if' 
blocks that do not make much sense to me and some have unbalanced
braces. Here an example of latter:

=== stack/ups_db/Linux64/qserv/6.0.0rc1/ups/mysqlpython.table ===
if (type == exact) {	
   setupRequired(python          -j system)
   setupRequired(mysql           -j 5.1.65)
} else {
   setupRequired(python system)
   setupRequired(mysql 5.1.65)
}
}                   # <----- extra brace???

envPrepend(PYTHONPATH, ${PRODUCT_DIR}/lib/python)
=================================================================

and here is an example of strange ifs:

=== stack/ups_db/Linux64/qserv/6.0.0rc1/ups/luaexpat.table ===
# luasocket build file relies strongly
# on lua 5.1
if (type == exact) {
if (type != exact) {
   setupRequired(lua -j 5.1.4)
   setupRequired(expat -j 2.0.1)
}
} else {
   if (type == exact) {
      setupRequired(lua             -j 5.1.4)
      setupRequired(expat           -j 2.0.1)
   } else {
      setupRequired(lua 5.1.4)
      setupRequired(expat 2.0.1)
   }
}
==============================================================

I tried to read about this "type == exact" ifs in 
https://dev.lsstcorp.org/trac/wiki/EupsTips and it looks to me that 
table files that come from http://datasky.in2p3.fr/qserv/distserver/tables/
are not supposed to have those ifs, they are added when table files
are installed. Maybe eups gets confused by the existing ifs in
table files when it does installation?

Cheers,
Andy
