Trying to build KDE I've encountered the next problem: it reports about
exhausting virtual memory on compiling addressbook.cc in kdelibs-1.1.1/kab
directory.
First there were 37M at /dev/sd0b and 56M at /dev/sd1b while real ROM is
17M. To be sure I've added 70M else at /dev/sd1a, so getting total amount
of virtual memory 163M.  After getting the same make log, attached here, I
decided to ask here what to do.

Here the make log file with some skip attached:
