When one does emerge -pvuDN @world | genlop -p, it can take forever to come back with the result. This is especially true if you have many packages on the list and a long emerge.log (mine dates back from early 2008)
Looking at the genlop code, I saw that the emerge.log is re-read for each package on the pretend list. This is bad, so I fixed it.
I've done the following:
# eix -I -C kde --format "<category>/<name>" > /tmp/tt
# wc -l /tmp/tt
# time cat /tmp/tt | genlop -pq
(running this last command multiple time and looking at average)
Original genlop 0.30.8-r2
The patch was build against the latest genlop (0.30.8-r2)

patch to improve the speed of genlop -p
I'm now sure how to proceed for this to get some attention. So I just add to the CC list email addresses I see in the genlop Changelog file?
i used your patch in genlop-0.30.8-r2 , works nice.
however i get following warning output :
emerge -p mc |genlop -p
These are the pretended packages: (this may take a while; wait...)

Could you gzip and attach your /var/log/emerge.log? Perhaps a package name or a special line is causing the precedent regular expression to crash...

As requested, the gzip compressed emerge.log
If you need anything else, let me know.
hum, your emerge.log is strange (no offense!)
starting at line 97346, you have:

As you can see, there are no "emerge (19 of 76) ..." line and the whole "18 of 78" block is missing too.
I can only speculate on why your emerge.log has such content, I'm not sure how it could have happen: fs corruption, emerge crashing, temporaty out-of-disk-space issue? I don't know.
All in all, the problem isn't in the genlop tool itself.
Have a nice day!
