 with -d I don´t see anything particular going on, it just keeps running
 until suddenly it stops:

 {{{

 DEBUG: nspr 4.7_1 is installed

 }}}

 The thing is, watching my memory usage, with istat widget, while it runs,
 it looks like no memory is being used at all until suddenly, it spikes.
 (this takes a while, I just check in every 15 minutes)  Its not a slow
 rampup on the graph, it is flat until it spikes.

 Another thing, I just want to check because its big, look at that malloc.
 Does it request half a meg each port, just to verify port versions?

 {{{
 sudo port selfupdate
 Password for admin:

 MacPorts base version 1.600 installed

 Downloaded MacPorts base version 1.600

 The MacPorts installation is not outdated and so was not updated
 selfupdate done!
 }}}

 I tried tcl just at 8.5.4 and with the +memdebug +threads ... just hoping
 that might be the issue.
