AMMRL: automation time incorrect in chempack4.0 - summary

I recently posted a problem that I was experiencing with vnmrj_1.1_D with
RedHat Linux 4.0. I received a lot of help from Dr. Krish Krishnamurthy (of
Eli Lilly), the automation time is correct when experiments are submitted.
here is the summary:
The problem I was experiencing was posted on the varian user library site
as:
PSG - Sequences may ignore delays in exptime calculation
Bug-ID: psg.j1111 (++,M)
Summary:
(Re-)Compiling any pulse sequence under RHEL 4 leads to an executable that
ignores the time of all delays during the calculation of exptime.
Consequently, all timing for manual and automatic data acquisition is
massively wrong, rendering StudyQ automation impossible. All macros and
commands that calculate the experiment time are affected (xm1('time'), time,
exptime). When actually starting the experiment, the correct remaining time
is displayed in the hardware bar, and the sequence works and gives proper
spectra. The pre-compiled pulse sequences from the VnmrJ installation CD-ROM
work OK, as do sequences that were compiled on a RHEL 3/32 bit Linux PC
(64-bit RHEL 3.2 was not checked).
Bad versions: VnmrJ 1.1D / RHEL 4 / MERCURYplus
Reported by: Bert Heise, Varian (2006-10-25)
Priority rating: P5 (high, "parked")
Status: Assigned
Workaround:
Use only the pre-compiled pulse sequences in /vnmr/seqlib or compile the
desired pulse sequence on a Linux computer equipped with RHEL 3, if
available.
Severity: 1 (Prevents use of system or software package)

Krish sent me a pulse sequences which he had compiled using RHEL 3 which I
replaced what I had in my /vnmr/seqlib and this solved the problem.
Thank you
