R SIG Fedora - Jun 2013 - tcktk problem with custom R 2.15.0 build on RHEL5

Bruce Pennypacker wrote that he was having a problem using the R library 
sqldf under Red Hat 5.6:


  > library("sqldf")

  > result<-sqldf("select data.*, meth450part.chromStart as
MethChromStart, meth450part.chromEnd as MethChromEnd, meth450part.strand
as MethStrand, meth450part.name as MethName, meth450part.score as
MethScore from data join meth450part where data.V1=meth450part.chrom and
data.V2<=meth450part.chromStart and data.V3>=meth450part.chromEnd")
Loading required package: tcltk
Error in structure(.External("dotTcl", ..., PACKAGE =
"tcltk"), class "tclObj") :
    [tcl] unknown math function "min".

I had the same problem as discussed in this thread. The problem is that sqldf
requires version 8.5 of tcl/tk and there is not an rpm of tcl 8.4.
What I did was:
1. Get version 8.5 of tcl for Linux directly from
ActiveState:http://www.activestate.com/activetcl/downloads
2. Tell R where the tcl 8.5 libraries are when you build R:
./configure --with-tcltk
--with-tcl-config=/opt/ActiveTcl-8.5/lib/tclConfig.sh
--with-tk-config=/opt/ActiveTcl-8.5/lib/tkConfig.sh
